unicode - Remove multiple BOMs from a file

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.

Answer 1

I normally do it using vim:

vim -c "set nobomb" -c wq! myfile
