[MCPE-164658] Indents appear when using the Unicode font and bold text

^{Update from [Mod] EVGENSYPERPRO}
Summary:
When using bold text with an Unicode font (languages using this font), indents appear on the right side. This can be seen on signs, when using the command /title, (less noticeable) in chat, books and possibly other texts.

Steps to reproduce:

Write any text in any field (for example on a sign) in the language using the Unicode font.

§lЭто тестовая надпись & Это тестовая надпись

Observed results:
The text has an indent on the right side.

Expected results:
Indents should not appear when using bold text with Unicode font.

Screenshots:

PMMP 4. When I use bold text in sendTitle, sendPopup, etc. (except for sendMessage) empty spaces appear; reset at the end of the line does not help either. Appear only in Cyrillic. In the screenshots, an example of text: §l§cЭто тестовая надпись & Это тестовая надпись
