dev/core#2789 - Filename is not non-english-friendly in print/merge document

[demeritcowboy]

Overview

https://lab.civicrm.org/dev/core/-/issues/2789

After #21006 the filename is now based on the activity subject, but this results in awkward filenames for non-english activity subjects.

Before

1. Search for contacts.
2. Choose print/merge document from the actions menu.
3. Fill out a non-english subject, e.g. ДДДДДД
4. When you download the filename is something like

French and similar languages aren't too bad, but accented characters get replaced.

After

Alphabetic characters in all languages are retained. Emojis and punctuation etc are replaced.

Technical Details

munge() is useful if the filename isn't human-visible, or for generating valid db table names. If the filename needs to be human-sensible it's not a good choice.
