Only standard Unicode characters are displayed properly

[m-ueberall]

If you use, e.g., the "Unicode Text Converter" (see here) in order to emphasise (parts of) your tweet, chances are that tweetnest will only show question marks for the respective pasted characters.

While arguably the use of special/non-standard characters should be minimised to begin with, "masking" them renders most of the tweets in question illegible.
