[PATCH] D47578: Do not enforce absolute path argv0 in windows

So the best practice is, when you get a UTF-16 string from an Windows API, you should convert it to UTF-8 as soon as you can so that you can always process strings as UTF-8. Likewise, you should always keep all string in UTF-8 in memory and convert them to UTF-16 just before passing them to an Windows API if necessary. If you find yourself writing UTF-8 ↔ UTF-16 conversion code too frequently, that's like a signal that you are not doing text processing in UTF-8. Basically you need to do coding conversion up to only once for each new string.
