Lua engine 5.3.0 support UTF-8 and add many new functions
@ DC: please consider update new Lua Engline!

http://www.lua.org/manual/5.3/readme.html

I agree.

Answer to the thread title: Never. Sorry.

Last time I messed with Lua (Lua JIT stuff) everything exploded. I really do not want to touch the Lua version. So an upgrade to 5.3. is extremely unlikely.

Background info: I would need a BlitzMax module for Lua 5.3.0 which is compatible with the current Lua BlitzMax module CS2D is using (PUB.Lua). As far as I know there is no such thing (BlitzMax is dead and not updated anymore) and I'm not willing to invest time to upgrade it on my own (it's an EXTREMELY annoying task).

We can use UTF-8 in CS2D as well.

@ Gaios:
Engineer ‘s utf-8 Lua have some big Bug and hook:say dont support chinese,
I think if CS2D support UTF-8 completely，It's will not have this trouble.
Lua 5.2 support utf-8,so I think it's a good way！

Need bit operations and new metamethods.

Replying 3-year-old threads for the win. Either way won't happen.

DC: stated a lot of times that he doesn't want CS2D game on Steam. But now the game is on the Steam platform. What do you say to that?

This is a dilemma of all forums - "what's better, to necropost or to create a duplicate thread?"

Necro posting is better.

A Lua engine upgrade still won't happen.

Upgrading to Lua 5.3 is useless, it just minor update. And also it will breaks the game's code, like shooting, spectating, EVEN script function wouldn't work because of this. Think twice before deciding something.

there's a workaround for Chinese Characters i think, i forgot how tho

Oh yeah and also there's people also workaround to make utf-8 support on Lua 5.1, i found this in Github tho. You can just import it and then wait for the module script to convert it.

I think CS2D staying at 5.1 is the best thing DC ever did because I develop a code injection that replaces CS2D stock Lua 5.1 with more powerful LuaJIT (see signature) and if CS2D changes its Lua version, it means my project no longer works because Lua 5.1 and 5.2 is not compatible between each other.

I wrote Lua code optimized for LuaJIT for living and I can say LuaJIT is all what you need to extend your server capabilities beyond what CS2D offer.
