Unable to minify JS files saved in Visual Studio about uglifier HOT 4 CLOSED

Could you send an example file? What JS runtime are you using?

I'm assuming that this is some kind of Byte Order Mark, but as I don't have access to Visual Studio it's a bit hard to debug.
You could try to save the file as "UTF-8 without signature".

@lautis wow! thank you so much. that is indeed the issue. is there a way to fix this in code without having to go the extra step defining saving with encoding? some of my users may not know to do this...

Yes, something can be done. It depends on how you are calling Uglifier, Ruby version and probably even on your JavaScript runtime.

On Ruby 1.9.2 you can open/read file with File.open('file.txt', "r:bom|utf-8").read and it should strip BOM. It also seems that using Node.JS as JavaScript runtime does work, but that may not be true on Windows.

I'll try to replicate this issue next week when I can access our office Windows testing PC. Stealing some BOM stripping code from Sprockets should solve this. https://github.com/sstephenson/sprockets/blob/master/lib/sprockets/utils.rb
