Description:
How to batch strip(remove) utf8 BOM of many files?
Answer:
Hint: You need to Download and install "Replace Pioneer" on windows platform to finish following steps.
utf8 BOM is byte order EF BB BF at the beginning of file, which is 0x{feff} after decoded with utf8.

For Replace Pioneer 2.2 and later, please use following link:
http://www.mind-pioneer.com/services/631_Replace_text_in_multiple_files.html

For earlier version, you can strip utf-8 BOM successfuly by removing leading \x{feff} in each file:

1. ctrl-h open 'Replace' dialog

in 'Replace' page:
* fill "unit number filter" as:
 means the 1st character
* enter search for pattern as a single dot:

* enter if as:
 means remove only if it is \x{feff}

select 'Settings' page:
* set Input Encoding to 'utf-8'
* set Output Encoding to 'utf-8'
2. If you want to process single file, just enter "input file" and "output file" and click 'Replace'.

3. If you want to process multiple files, click 'Batch...' button, and:
* click 'Pick Files' to select multiple file to process
* click 'Batch Replace', all files will be processed automatically
