I came across this utility while looking for a way to remove Unicode from file names, and a thread told me to do this.
[^\x00-\x7F]+/g In the Regex box.
Works great for the most part.
What i found is that it works where the unicode is somewhere inside the filename, but NOT if the unicode is the FIRST character of the file name, it seems to leave them alone.
Example is, ???? Termy, wracaj do domu! Gigantozaur Disney Junior Polska. It will not do that. But if it was Termy, wracaj do domu! ???? Gigantozaur Disney Junior Polska, then it would work.
