After a few hours I came up with this, which works:

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 ')

 

Should not the answer rather be 11?

And would not

function end_of_string_literal(word,quote)
   local pattern = '()%b' .. quote:rep(2) ..'()'
   return select(2,word:match(pattern))
end

be somewhat simpler?

It says "end". It implies you already know the start.

"\""

function end_of_string_literal (text, start_pos, quote)
   return text:gsub("\\?.", {[quote]="\0"}):match("%z()", start_pos)
end
 
print(end_of_string_literal ([[a="\"A",b="\\\"B\"",c="C"]], 4,  '"'))  --> 8
print(end_of_string_literal ([[a="\"A",b="\\\"B\"",c="C"]], 12, '"'))  --> 20
print(end_of_string_literal ([[a="\"A",b="\\\"B\"",c="C"]], 24, '"'))  --> 26
