Hi
Does anyone know what's coming up in terms of
support for Unicode (e.g. UTF-8) in Lua? This is my current understanding
- please correct me if I'm wrong:
1. Lua scripts are currently always written in ANSI
only, and probably always will be.
2. Strings in Lua
can be in any format you like (e.g. ANSI, UTF-8 or UTF-16) so apps that
want to support Unicode can do so by specifying
that string parameters and return values are in a Unicode encoding such as
UTF-8.
3. There is currently plenty of library
support for ANSI Lua strings, but no library support for working
with UTF-16 Lua strings. There are one or two small libaries for
doing some simple string manipulation with UTF-8 strings (e.g. http://lua-users.org/wiki/ValidateUnicodeString and
http://files.luaforge.net/releases/sln/slnunicode).
UTF-8 is likely to have more support in the future in Lua libraries than
UTF-16.
4. IUP currently only supports ANSI Lua strings,
but support for UTF-8 Lua strings will be added soon? Is that right?
Any timescales on that?
Is the above correct? Anything important I
haven't mentioned?
I'm a great fan of Lua. Support for Unicode
is really important for me though. The above strategy, if correct, is
probably OK for my purposes. Ideally I'd prefer script-writers to be able to
write scripts in UTF-16 and work entirely in UTF-16 - but I can live
without that. But it will only really work when support for UTF-8
becomes available in IUP - and, ideally, other Lua libraries. So does
anyone know what work, if any, is currently being done on adding
support for UTF-8 (or UTF-16?) Lua strings in Lua libraries - such as
IUP?
TIA
Simon
