[why]
The Box Drawing glyphs need to be carefully scaled. This can not be done if the glyphs are pulled in via font-fallback I guess.
As people may have the fontconfig set up in a way to prefer the Symbols Only font these glyphs could overrule other box drawing glyphs that might fit better.
I'm not really sure about this one, but the glyphs look rather bad anyhow, because they end up in the 1:1 ascpect ratio cell of the Symbols Only font.
[how]
Just turn the set off if we patch the Symbols Only font. Need to swap around two subroutine calls for that; first detect if we are patching the Symbols Only font (through the font metrics) and then set the patch sets up.
Fixes: #1210
