Using obfuscated text does not work with Unicode font

Summary:
When using §k (obfuscated text) does not show correctly with the Unicode font. Obfuscated text is displayed as points when using unicode font, which makes it impossible to use a obfuscated text when using a language with unicode font. The same problem has a Noto Sans font in a chat - MCPE-95142.

Steps to reproduce:

1. Write (In any text window supporting formatting) something in the language using Unicode font and use obfuscating.

§kЭто тестовая надпись

→  . . . . . . .. .

Observed results:
The text will turn into points.

Expected results:
Font should either obfuscate correctly, else render without formatting if technically impossible.
