semicolons in names (valid?)

I ran into a "bug" where I assumed semicolons weren't valid in names/identifiers (just word characters, hyphens, underscores, the lua definition of things). Figured I would ask here, if anyone knew whether or not semicolons were supposed to be "valid" in names/categories/etc; if there were any solid definition anywhere.

A semicolon may optionally follow any statement. Usually, I use semicolons only to separate two or more statements written in the same line, but this is just a convention. Line breaks play no role in Lua's syntax; for instance, the following four chunks are all valid and equivalent:
a = 1
b = a*2
a = 1;
b = a*2;
a = 1 ; b = a*2
a = 1 b = a*2 -- ugly, but valid

I can look up how
lua handles things, but Factorio will handle things its own way. I'm hoping there's a Factorio reference and not "if it works it's valid"

Strings dont matter.
Semicolons and practically anything can be used as a prototype name.

Those are the only restrictions given by Factorio.

Now i wonder, is that 200 characters or 200 bytes? Some languages have multi-byte characters ;)

You. Cut that shit out. I had to rewrite a function because I needed to empty a table and instead assigned the
local variable to the empty table. It's bad enough using pairs() over a table you're modifying is undefined behavior.

I have no fucking clue what you're talking about. But please calm down.

You probably mean grapheme clusters.
Who would care about single code points anyway...
