The vast majority of script names in FC-generated glyph names adhere to the 4-letter format, with notable exceptions:
-canadianaboriginal
-chorasmian
-cuneiform
-divesakuru
-elymaic
-khitansmallscript
-nandinagari
-nyiakengpuachuehmong
-wancho
-yezidi
While “-wancho” isn’t that much longer than, say, “-ugar”, and thus easy to display - having a 2-letter name, followed by a 20-letter script designation (as in e.g. “ma-nyiakengpuachuehmong”), could, imho, benefit from a do-over.
