[Feature]: Support NerdFont double-width characters

[ErrrorMaxx]

Feature description

If I install NerdFont-patched font (i.e. JetbrainsMono) 'Mono' variant (Where all nerdfont symbols are monospaced) everything is ok.

But if I install not 'Mono' variant of font, some icons are vertically stretched, because they must be displayed as double-width characters, but they aren't
