Question

I am using a Javascript file that is a concatenation of other JavaScript files.

Unfortunately, the person who concatenated these JavaScript files together did not use the proper encoding when reading the file, and allowed a BOM for every single JavaScript file to get written to the concatenated JavaScript file.

Does anyone know a simple way to search through the concatenated file and remove any/all BOM markers?

Using PHP or a bash script for Mac OSX would be great.

To remove multiple BOMs from anywhere within a text file you can try something similar. Just leave out the ^ anchor:

perl -e 's/\xef\xbb\xbf//;' -pi~ file.js

(This edits the file in-place. But creates a backup file.js~.)
