Mod's version

1.20.1-1.6.2 (I haven't checked, but I think it can occur for any newer version)

Issue

Malum's ‎‎book renderer shows \u200e Unicode control character (it should be invisible) after guillemets (« and »), which are considered primary symbols for quotation marks over basic latin quotation mark in many languages.

Thoughts

I think it happens because of one specific property of guillimets. The symbol is used not only in Left-to-Right languages (Russian, French and etc.) but is used in Right-to-Left languages as well (Arabic).

\u200E symbol ensures, that the text is rendered in right direction, but the symbol itself, of course, shouldn't be rendered.

Solutions I see:

1. Clean text from added \u200e (LRM) and \u200f (RLM) as I don't see translations in other languages using guillimets as much (if they do at all) as translations in Russian
2. Handle characters (\u200e in this case) that should be invisible

What doesn't work:

1. Workaround: changing guillimets to their unicode (\u00ab and \u00bb). If space or end of the line occurs after guillimet unicode, \u200e would still show up.
