Yes, if the absence of glyphs can cause crashes, the most likely source
of trouble is that some sequence in the iso-scan main menu string is
shaped to a code point that's missing from
installer/build/needed-characters/ar. This *should* have been a
complete list of all characters generated by the shaping code, but it's
not impossible that I missed one.
