Support for unicode-escape style path strings

[The-Keeper]

FileWriteN currently doesn't perform replacements to a unicode-escape style strings (\x-escaping for non-ANSI characters) which results in "file not found" errors when a user moves the portable app directory to a path that has non-ANSI characters.

Is there a specific app that needs this functionality? I don't think I've encountered it in the hundreds of apps I've worked on. You can likely do it via custom code, which is how we handle most edge cases.

Sorry, I just realized no one addressed this.
