The task is to simplify Sony's code:

I would have participated more enthusiastically if the OP had provided
(a) a decent description of what the code is supposed to do
(b) a nontrivial example of input and expected ouptut
(c) an indication of what word_eol[2] means

You have now provided (a) and (c), but my enthusiasm flickered
out long ago.
The Lua test suite is a good place to find nontrivial examples of input and expected output, at least once the string goes through the rest of the parser, which turns the string literal into a string. 




local m, pos
repeat
   m, pos = string.match(word_eol[2], "(\\*)"..cw:sub(1,1).."()", pos or 2)
until m == nil or #m % 2 == 0

(cw:sub(1,1) being one of " or ')

What this code does?
It is probably a part of some parser (or should I say scanner?)
A text (in variable word_eol[2]) starts with quote-delimited string literal
(the quote is cw:sub(1,1))
This code finds the position where the string literal terminates.
String literal syntax implied here is allowing backslash escaping.
