term: ignore LTR+RTL markers (U+200E + U+200F)

Browse source 
Foot doesn't implement RTL, and explicit LTR markers is neither
needed, nor used in anyway. In fact, they cause issues with font
lookup, as fcft often fails to find the marker codepoint in the
primary font, causing a fallback font to be used instead.

Closes #2049
