# the "ini" library for locale has many quirks
#  * `a="xx"` gets `xx` (no quote)
#  * `a=x\"y` gets `x\"y` (no unescaping)
#  * `a="x\"y"` gets `"x\"y"` (no unescaping, the quotes are still there)
#  * `a='x\"y'` gets `x\"y` (no unescaping, no quote)
#  * `a="foo` gets `"foo` (although the quote is not closed)
#  * 'a=`foo`' works like single-quote
# crowdin needs the strings to be quoted correctly and doesn't like incomplete quotes
# crowdin always outputs quoted strings if there are quotes in the strings.

# this script helps to unquote the crowdin outputs for the quirky ini library
# * find all `key="...\"..."` lines
# * remove the leading quote
# * remove the trailing quote
# * unescape the quotes
# * eg: key="...\"..." => key=..."...
