textproc/lua-utf8 0.1.5 NetBSD

This module adds UTF-8 support to Lua. It's compatible with Lua's own string module, and passes all string and pattern matching tests in Lua's test suite.

It also adds some useful routines against UTF-8 features:

• a convenient interface to escape Unicode sequences in strings.
• string insert/remove, since UTF-8 substring extract may be expensive.
• calculate Unicode width, useful when implementing e.g. console emulator.
• a useful interface to translate Unicode offsets and byte offsets.
