A collection of small Lua modules implementing some if the most generic Unicode algorithms for use with LuaTeX.
This package tries to reduce duplicated work by collecting a set of small utilities which can be used be useful for many LuaTeX packages dealing with Unicode strings.

(This example is shown in Latin Modern Mono which has the (for this purpose) very useful property of not handling combining character very well.
In a well-behaving font, the `...C` and `...D` lines should look the same.)
-Additionally for NFC direct normalization of Lua\TeX\ node lists is supported.
+Additionally for direct normalization of Lua\TeX\ node lists is supported.
There are two functions |normalize.node.NFC| and |normalize.direct.NFC| taking upto four parameters: The first parameter is the head of the node list to be converted.
The second parameter is the font id of the affected character nodes. Only non-protected glyph nodes of the specified font will be normalized. Pass |nil| for the font
to normalize without respecting the font in the process. The third parameter is an optional table. If it is not |nil|, normalization is supressed if it might add glyph
which map to |false| (or |nil|) in this table. If the forth argument is |true|, normalization will never join two glyph nodes with different attributes.
+For NFD and NFKD equivalent functions exists without the last parameter (since they never compose nodes, they never have to deal with composing nodes with different
+attributes.

+NFKC is not supported for node list normalization since the author is not convinced that there is any usecase for it. (Probably there isn't any usecase for node list
+NFKD normalization either, but that was easy to implement while NFKC would need separate data tables.

For case folding load the Lua module |lua-uni-case|.
