I have a Node.JS application which currently does not allow Unicode characters in filenames. I'd like to go ahead and start allowing certain characters. For example Café or 你好 would be allowed as filenames.
However, I know that NUL character attacks are possible, and there are potentially bothersome control characters. Really all control characters (and most most non-printable characters) should be blocked.
To start with, I was planning to obtain some of the ranges of 'safe' unicode characters and code them in manually. However, is there a quicker way? Perhaps all the file-system safe ranges are already listed somewhere I can easily obtain?
