(But I have no idea if that makes sense.) > Here's what describe-char shows on both: That says you have a single grapheme cluster in both cases. Does the cursor include all of the characters in both cases? IOW, can you move with C-f between these 3 characters, or do they behave as a single character cell in both cases? If the latter, then the composition was done in both cases, and you simply should find a better font if you want these displayed more nicely.
