Generic way to check validity of file name in Python?

Creating a file can fail in Python because of various file name related reasons:

1. the file path is too long (see e.g.: what-is-the-maximum-length-of-a-file-path-in-ubuntu )
2. the file name may be too long, as the file system is encrypted – see e.g. comment in answer to that question:

On encrypted filesystems the max filename length is 143 bytes. 
To decide whether a filename is short enough you can find his byte length in Python 
with len(filename.encode()). –

3. there are characters that either make issues in the file system, are not recommended or could make issues in another file system like:  \n!@#$%^&*()[]{};:,/<>?\|~=+`

Is there any convenience function that tells me beforehand whether

• a) my file name will work
• b) may lead to issues in other file systems
• c) and why it will fail?

Solutions like:
Check whether a path is valid in Python without creating a file at the path's target
or
Validate a filename in python

unfortunately do not fulfill the requirements a) – c) (even the first one does not recognize the 143 character restrictions for encrypted folders / drives)

>Solution :

If external package are allowed I suggest you try pathvalidate, function validate_filename should be of interest if you need to find why it will fail? whilst is_valid_filename if you need to find if file name will work
