[solved] SentenceCase not recognizing accented letters

Firstly, I apologise if this was already asked. I'm not familiar with this website and the search seems quite glitchy.

Anyway, I'm trying to make a generator that will (amongst other things) create a basic Chinese 'name' in pinyin. Without tones is no issue. With tones, well, there's a problem.

I can get all lowercase outputs just fine, and when the first letter is not accented, its also just fine. But if the first is accented, the output skips the accented letter and then capitalizes the SECOND letter.

For example,

tè áobǎ

Becomes this:

Tè áObǎ

When I actually want this:

Tè Áobǎ

I'm sure there is probably some fancy pants way to check if a letter is the first in the word and then substitute for the right letter, but, I am new to perchance, and my current searching hasn't yielded any results on how this could be done.

Something like checking the first letter of the sentence case against a list of symbols, then using the substitute? (I'm not a coder, and I don't know how to do this!)

my current code, barely worth even sharing:

output = [sentence]

sentence
  [pinyin.sentenceCase] [pinyin.sentenceCase][pinyin]
