Save to disk, characters getting replaced by _

[abuck]

I have some title with '+' characters in it and when I save to disk, It's getting converted to underscore _. I'm not sure why it can't save as '+' characters and need to convert any occurance of '+' to '_'.

Is there any reason for this ? Can I remove this convertion, I would like to have '+' instead of '_' in my pdf filename.

An example would be: C++ for dummy.

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

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.

No, you cannot. The list of filtered out characters is designed to be robust across *all* currently used operating systems, kernels and file systems.

Is there any file I could change (python) or any hack to bypass this ? It's stripping off my . in the filename and I'm using another program to compare it so I need to make sure the file does not get change.

I'm a programmer so any plugin or any custom stuff I could bypass this auto-rename would be such appreciated.

thanks!

Run calibre from source, and change the sanitize_file_name functions in calibre/__init__.py

Your solution worked perfectly !
