Repair of sabotaged mathematical glyphs in certain Linux distros.

Recently, I received a tip that some Linux users saw rubbish in place of certain Unicode glyphs appearing in the FFA series (in particular, in Ch. 14.) If the following two rows of symbols do not appear recognizably-identical in your WWW browser: ← → ⇠ ⇢ ⌊ ⌋ … the following fix is likely to […]
