So what, I have dozens of files and folders with '++' in their names - I use it to give me a hint that said file or folder contains something extra than the name might otherwise indicate.
See
Naming Files, Paths, and Namespaces
Quote:
Use any character in the current code page for a name, including Unicode characters and characters in the extended character set (128–255), except for the following:
The following reserved characters:
< (less than)
> (greater than)
: (colon)
" (double quote)
/ (forward slash)
\ (backslash)
| (vertical bar or pipe)
? (question mark)
* (asterisk)
Integer value zero, sometimes referred to as the ASCII NUL character.
Characters whose integer representations are in the range from 1 through 31, except for alternate data streams where these characters are allowed. For more information about file streams, see File Streams.
Any other character that the target file system does not allow.

I don't use the '++' hint in calibre because I can put a note into My Comments column and spell out what the extras actually are.
ETA : Are calibre's file naming 'rules' concisely documented anywhere - including which are platform specific and which are global. I looked in the manual but couldn't see anything.
