replace hyphen in filenames to underscore inligatures

[mav-rik]

I noticed that when I am using files with hyphens (like arrow-up.svg) then the ligature method does not work.
I always have to rename files to have underscore instead of hyphens.
I am not sure if it is ligatures limitations or is it I doing something wrong. But the option to automatically replace hyphens with underscores would improve my experience a lot.

Is it something we can add to this repo?

Sorry for the veeeeeery late response.

Hyphens (-) should be replaced by an underscore (_) and any non alphanumeric character should be removed.

If this isn't the case, please provide an example.
