%description
This module adds UTF-8 support to Lua.

It uses data extracted from the
[Unicode Character Database](http://www.unicode.org/reports/tr44/),
and is tested on Lua 5.2.3, Lua 5.3.0 and LuaJIT.

parseucd.lua is a pure Lua script to generate unidata.h, to support conversion
of characters and to check the category of a characters.

It is compatible with Lua's own string module, and it passes all
string and pattern matching tests in the lua test suite.

It also add some useful routines for UTF-8 features, including:
- a convenient interface to escape Unicode sequences in string.
- string insert/remove, since UTF-8 substring extract may expensive.
- calculating the Unicode width, which can be useful when implementing a
  console emulator.
- an interface to translate Unicode offset and byte offset.
