Subscript entity in the name of files or some advise for alternatives

[Ypo]

Hi

I tried to don't get the subscripts (_) affected by org-pretty-entities.

I wanted it, because I usually use (_) to divide words when naming my_files, and that looks ugly in Orgmode.

I have tried redefining the constant org-match-substring-regexp, but I think that broke several other things 😅

Is it possible to use org-pretty-entities without altering subscripts (_)?

Should I avoid using (_) in the naming of files?

Another option could be to use symbols instead of LaTeX syntax: writing Π instead of /Pi. This solution could be more universal, since external "org" interpreters like orgzly could show Π while maybe they will never show \Pi appropriately.
