Determine if a file is Unicode or ANSI

I have a bunch of INF files that I'm trying to work with. The problem I'm finding is that some of them are Unicode format and some are ANSI.


I can open and read in the file fine, but when I try to write out to it, my script crashes.

VB Code:

Set outFile = FS.GetFile(FSFile.Path).OpenAsTextStream(2, -2) 'save INF in ANSI format to save space
outFile.Writeline FileString 'write the modified text
outFile.Close 'close file handle
set OutFile = Nothing

If I write a null value to the file it seems to work fine.

I also found out that it is crashing due to invalid characters. The Unicode format supports a larger character set than ANSI. The INF file I have contains Chinese characters which are causing the script to choke when it tries to write them out to the ANSI file.

Now, the question is... is there a way to convert these Unicode characters, without going through each and every character in the string and testing it? Ugh... there must be an easier way.

Heck I'll even settle for a batch file if it gets the job done.
