Problematic handling of apostrophe in scintillua lexers

[mcepl]

English language uses apostrophes quite often (a way more often than other languages I know) not only as a substitute for double quotes, but also in normal text (namely, The Saxon Genitive). The result is that the string definition as it was originally in the org lexer (and many others) doesn’t work very well:

-- Strings.
local sq_str = P('L')^-1 * lexer.range("'")
local dq_str = P('L')^-1 * lexer.range('"')
lex:add_rule('string', lex:tag(lexer.STRING, sq_str + dq_str))

Every English possessive breaks the highlighting (with home-made lexer, which includes this construct):

I am not sure how to fix it.

A simple fix would be to not match single quoted ranges. I'd be curious how org mode handles parsing of single quotes if it supports both single-quoted strings and bare apostrophes.
