Is there any option to quick select?

Here is the thing I need to do:

  • Select a language category in the sidebar.
  • Only keep the characters in this category, delete all others (only keeps the necessary component characters, such as used diacritics and basic latin alphabet)

Is there a really fast way to do that? Or I must manually select glyphs (which is a pain, in case your font file has >1000 characters).

What I usually do is to set all glyphs to one color, then remove it from all glyphs I like to keep and the add a filter that shows all glyphs with the color set.
