I settled on the Yahoo YUI Compressor, in particular, the .net port of it
When I tried to compress a particular file (the jquery.caret plugin), it would throw up a syntax error.
This error only occurred using the .net port of Yahoo YUI Compressor.
Using the standard java jar version of YUI Compressor did not throw such an error.
The error was a syntax error on this line:
It was saying invalid character at position 0.
After some time scratching my head, I opened the file in notepad++ and converted text to hex 16
Immediatlely, I could see there were some invalid characters around the function text:
Removing those characters and saving the file solved my problem, and allowed the file to compress.
I looked at the issues page for the jquery.caret project, and found this issue had already been reported
I’ve created an issue on the codeplex page for this now:
