Although spell-check for Romanian is enabled and the auto-correct options should follow that spell-check language, what happens is that i is changed automatically (auto-corrected) to I just like in English. A such auto-correction is not present for Romanian. It is for US English.
If I want to write something like Ei i-au spus (“They told him”), when I write - after i the auto-correction produces I- (the same letter but uppercase) instead of i- and I get the incorrect if not biblical Ei I-au spus (‘They told Him’, as if ‘they’ were talking to God.) It is in fact the English auto-correction from i to I (like in I am).
Also, i is changed to uppercase after clicking space after it (only that i alone is not a word in Romanian.
I have tested with different common fonts. It does not seem font-related.
