Review Comment:
**\uFEFF** is the UTF-8 BOM (Byte Order Mark), a special non-printable
character that usually appears at the start of files saved in the UTF-8 with
BOM encoding. (Tools such as Notepad and Excel on the Windows system often add
this mark automatically when saving files in UTF-8 format.)
