LUA definition of an identifier seems not strong enough for a configuration file: > Names (also called identifiers) in Lua can be any string of letters, digits, and underscores, not beginning with a digit. This coincides with the definition of names in most languages. (The definition of letter depends on the current locale: any character considered alphabetic by the current locale can be used in an identifier.) config file being essentially KV pairs, thay means that certain property names are not valid or won't be valid if loaded by someone living in "country-with-strange-locale-istan".
