Glyph for U+23B5 (BOTTOM SQUARE BRACKET) missing

I just switched to `Departure Mono` after having heard about it in the Changelog.

I like it so far, though am missing the glyph from the issue title. I use it in my editor to signal trailing spaces.

The current replacement is acceptable, though I'd appreciate if the symbol gets added.

Alternatively I appreciate a suggestion for a similar glyph that I can use instead.
