All four way are in Tehran, and very probably they are all my fault. I
just fixed them.

All are of course typos, but the reason they arise is that the
character ZWNJ is used frequently in Persian, and is at the same time
invisible among Latin letters (it's a character that breaks joining
between letters of the Arabic and Indic scripts). I should have
accidentally pressed the key for the character when my keyboard has
been in Persian mode, and then, since I could not see any resulting
character on the screen, didn't notice it.
