ID 432196 - [C] Export: Fails if export file naming convention is set to include Sequence, Show, or Episode title with slashes

Problem summary
Slashes in the title for a Sequence/Show/Episode cause issues when exporting/publishing, if the export/publish file name is set to include [sequence_title], [show_title], or [episode_title].

Customer reported version
flix_6.2.2

Customer reported platform

Multiple

Steps to reproduce

1) In the export preferences, set the filename format for Artwork and Image to contain the [sequence_title] chip.

2) Create a Sequence named, for example, "abc/def".

3) Add a panel to this Sequence.

4) Export Image out of this Sequence. The export will not be successful.

Expected behaviour
The export should be successful.

Actual behaviour
The slash in the Sequence title is preventing the exported files from being named as set in the Preferences, and being moved to the specified export directory.
In 6.2.2 the files can be found in the local Asset Cache Directory, in 6.3.2 the export does not happen at all.
On Windows, both forward and back slash cause the issue. On macOS, only the forward slash causes the issue.

Workaround
Do not use [sequence_title], [show_title], or [episode_title] chips in file naming conventions if there are slashes in the titles.

OR

Do not use slashes in title and replace with another character instead.
