+*unicode.txt* A completion plugin for Unicode glyphs
+
+Author: Christian Brabandt <cb@256bit.org>
+Version: 0.17 Thu, 15 Aug 2013 08:53:06 +0200
+ *unicode-copyright*
+Copyright: (c) 2009 - 2013 by Christian Brabandt
+ The VIM LICENSE applies to unicode.vim and unicode.txt
+ (see |copyright|) except use unicode instead of "Vim".
+ NO WARRANTY, EXPRESS OR IMPLIED. USE AT-YOUR-OWN-RISK.
+
+==============================================================================
+ *unicode-plugin*
+1. Functionality
+
+This plugin was written to enable an easier use of any Unicode glyph
+available. The unicode.vim Plugin uses the data available from the Unicode
+Consortium's website (http://www.unicode.org) to let you enter Unicode
+characters using a completion function.
+
+By default, the plugin creates a directory unicode below the path autoload
+where this plugin is located. Within this directory it will store the file
+UnicodeData.txt from http://www.unicode.org/Public/UNIDATA/UnicodeData.txt
+which it will try to download using |netrw| . If this is unsuccessfull, or
+you do not have |netrw| enabled, dowload the file manually and save it in the
+unicode directory below the autoload directory in which unicode.vim is
+located.
+
+
+ *:EnableUnicodeCompletion*
+By default the plugin is not enabled. To enable it enter: >
+
+ :EnableUnicodeCompletion
+
+When you run this command, unicode.vim checks for the availability of
+UnicodeData.txt from the Unicode Consortium, and if it is not available,
+it will try to download it.
+
+This will also set up the completion function |completefunc| to use for your
+buffer. You can use |i_CTRL-X_CTRL-U| then to start the completion.
+
+ *:DisableUnicodeCompletion*
+If you want to disable the plugin, enter >
+
+ :DisableUnicodeCompletion
+<
+ *:UnicodeName*
+Suppose, you want to know, what the Unicode Name for the Character under the
+cursor is. You simply enter the ex command: >
+
+ :UnicodeName [reg]
+
+The plugin will then output the character, the character's hexadecimal value
+and the official Unicode name.
+
+Additionally, if there exists a digraph for that character, it will also be
+shown in paranthesis.
+
+If you specify a register name, the message will also be saved into that
+register.
+
+ *:Digraphs*
+>
+ :Digraphs
+
+Outputs the digraph list in an easier way to read with coloring of the digraphs.
+
+If you want to display a list with a line break after each digraph, use the
+bang attribute >
+
+ :Digraphs!
+
+And if you want to display all digraphs matching a certain value, you can add
+an argument to the command: >
+
+ :Digraphs! A
+
+displays all digraphs, that match 'A' (e.g. all that can be created with the
+letter A or whose digraph matches the letter 'A'.
+
+==============================================================================
+ *unicode-plugin-usage*
+2. Completing Unicode chars
+
+If you have enabled the plugin using |:EnableUnicodeCompletion| then there are
+2 possibilities to use the plugin. You can either enter the Unicode Character
+name, or enter the Unicode-Codeposition.
+
+For example, you would like to enter Æ, so you enter AE and press |<C-X><C-U>|
+while in insert mode. Alternatively you can enter the Unicode-Codepoint: U+C6
+and press |<C-X><C-U>| and the popup menu will show you all characters, that
+have a codepoint like C6 with leading zeros, eg. U+00C6 and U+0C66
+
+A popup menu will appear, showing you the Unicode-Codeposition value, the
+Unicode Character Name and the Unicode Character (and if you have enabled it,
+it can also show you the digraph characters needed to create this character in
+paranthesis, see |unicode-plugin-config| ). You can scroll down in the menu by
+pressing <C-N> and up by pressing <C-P>.
+
+A |preview-window| can be opened, if your Vim was compiled with the
+quickfix-feature that displays the hexadecimal Unicode Codepoint, the name,
+the digraph characters in parenthesis (if they exist) followed by the glyph
+itself by setting the variable g:UnicodeShowPreviewWindow (see below). By
+default, this feature is off.
+
+ *unicode-plugin-config*
+The plugin can be customized to include the 2 digraph characters you have to
+type, to get that character. This works only, if there is a digraph defined
+for that Unicode char. If you would like this you need to set
+g:showDigraphCode, e.g. >
+
+ :let g:showDigraphCode=1
+
+This functionality is by default disabled, cause it seems to cause some delay
+and screen-rendering errors in the menu. However, the preview window will
+always show the digraph character in parenthesis.
+Enter >
+
+ :let g:showDigraphCode=0
+
+to disable the Digraph feature afterwards.
+
+If you would like to specify a different URL from which to download
+UnicodeData.txt, enter the URL as: >
+
+ :let g:unicode_URL='http:....'
+
+To force downloading the file from that new url, enter >
+
+ :call unicode#CheckUniFile(1)
+
+If you'd like Unicode completion to be always enabled, you can set the
+variable g:enableUnicodeCompletion to 1 in your |.vimrc| like this: >
+
+ let g:enableUnicodeCompletion = 1
+<
+Thus, you won't need to use EnableUnicodeCompletion, it will be already
+available.
+
+If you only want to complete the Unicode Names instead of the glyphs,
+you can either set the global variable >
+
+ let g:unicode_complete_name = 1
+<
+or you can use the mapping <leader>un which swaps the completion function
+between completing the unicode name and completing the unicode glyph.
+
+If you want the completion of the unicode chars to be opened in the preview
+window, set the variable >
+
+ let g:UnicodeShowPreviewWindow = 1
+<
+in your |.vimrc|.
+
+ *unicode-plugin-error*
+If the plugin gives an error or does not complete anything, first check, that
+UnicodeData.txt from the Unicode Consortium has been successfully downloaded.
+It should be located below the autoload/unicode.vim script in a directory
+called unicode. So if you have installed unicode.vim into
+/home/user/.vim, UnicodeData.txt should be located at:
+/home/user/.vim/autoload/unicode/UnicodeData.txt and should look like this:
+
+0020;SPACE;Zs;0;WS;;;;;N;;;;;
+0021;EXCLAMATION MARK;Po;0;ON;;;;;N;;;;;
+0022;QUOTATION MARK;Po;0;ON;;;;;N;;;;;
+0023;NUMBER SIGN;Po;0;ET;;;;;N;;;;;
+0024;DOLLAR SIGN;Sc;0;ET;;;;;N;;;;;
+0025;PERCENT SIGN;Po;0;ET;;;;;N;;;;;
+0026;AMPERSAND;Po;0;ON;;;;;N;;;;;
+0027;APOSTROPHE;Po;0;ON;;;;;N;APOSTROPHE-QUOTE;;;;
+0028;LEFT PARENTHESIS;Ps;0;ON;;;;;Y;OPENING PARENTHESIS;;;;
+0029;RIGHT PARENTHESIS;Pe;0;ON;;;;;Y;CLOSING PARENTHESIS;;;;
+[...]

+
+If the file looks correct, and the plugin is still not working correctly
+contact the maintainer. You'll find his email-adress in the first line of this
+document. Please be patient, it might take a while, until I can take care of
+your report.
+
+==============================================================================
+ *i_CTRL-X_CTRL-G* *digraph-completion*
+3. Completing digraphs
+
+CTRL-X CTRL-G Search for the character in front of the cursor and
+ try to complete this letter using a digraph. If there
+ is no letter in front of the cursor, a list with all
+ available digraphs is shown in a popup menu.
+ If both letters in front of the cursor form a digraph,
+ that digraph will be completed.
+ (Think of Glyph)
+ CTRL-N Use next match. This match replaces the previous
+ match.
+ CTRL-P Use previous match. This match replaces the previous
+ one.

+ Szamotulski, thanks!)
+ 0.16: Feb 16, 2013 - |:UnicodeName| returns html entity, if possible
+ 0.15: Feb 05, 2013 - make sure, the returned digraphs list is not empty.
+ 0.14: Dec 01, 2012 - |:Digraphs| for better display of digraphs
+ 0.13: Sep 08, 2012 - better output for |UnicodeName| (did previously hide
+ messages)
+ 0.12: Apr 12, 2012 - |UnicodeName| shows digraph, if it exists
+ - better completion of digraphs
+ 0.11: Apr 11, 2012 - prevent loading of autoload file too early
+ - Make matching digraph more error-prone
+ - show all matching digraphs for a char
+ 0.10: Dec 15, 2011 - enable completing of only the names
+ - Really disable the 'completefunc' when disabling
+ the function
+ 0.9: Jul 20, 2011: - |:UnicodeName| checks for existence of
+ UnicodeData.txt
+ - |:UnicodeName| now also detects combined chars
+ - |:UnicodeName| now also outputs control chars
+ 0.8: Sep 30, 2010: - Fix an issue with configuring the plugin (Thanks jgm)

+ - Make use of the preview window, when completing
+ Digraph or Unicode Glyphs
+ - By default, the Digraph Glyphs will now be enabled
+ using |i_Ctrl-X_CTRL-G| instead of using
+ Ctrl-X_Ctrl-C which wouldn't work in a terminal
+ - |:UnicodeName| now displays the hexadecimal Unicode
+ Codepoint instead of the decimal one (as this seems
+ to be the official way to display unicode
+ codepoints).
+ 0.7: Sep 23, 2010: - |:UnicodeName|
+ - specify g:enableUnicodeCompletion to have unicode
+ completion always enabled.
+ 0.6: Aug 26, 2010: - many small bugfixes with regard to error-handling
