At the beginning of the line, the character EF BB BF (Byte Order Mark (BOM)) is copied, how to remove it?

Question

PHP

For some users, when pasting the data on the site, this symbol is also copied, it also gets into the database. Further, in programs that do not know how to process them, different characters are shown.
In fact, this is already an extra character at the beginning of the data, the nature of its appearance is notepad (but not all in a row).
On the site, of course, it is not visible, but if you search in general for various data on the site (s), then it is.
Who faced him? how to process and clean it properly.

Answer 1

Delete BOM
