UnmappableCharacterException happens when patching FTL 1.01-1.5.13 if a mod contains an unusual character that the game wouldn't display correctly - had patching been allowed to finish.

Selecting a mod and clicking the "Validate" button should identify any problematic characters for the mod developer to remove.

FTL 1.6.1+ is less picky about characters, so Slipstream won't throw an error in that case. It's possible that mods intended for - or only tested with - FTL 1.6.1+ may incidentally have a character that breaks backwards compatibility with the older editions.

Either way the dev should be notified.
