I have a monaco font patched for powerline that I downloaded from this repository. Now for licensing issue there are no free version of this font. Anyway, I use tmux which have
U+2502 as a separator for vertical split. Now, the monaco font that I have doesn't have this glyph.
I have another font, official latest version of Inconsolata that has a beautiful version of this glyph. I ran into this post from a while ago where one of the answers was to patch the font with that glyph manually with fontforge or similar font editor.
How do I just add one glyph to one font from another font?
