Hi Mustafa,

Typos:
s/Langague/Language/ (end of 1st paragraph, section A. Characters)
Just before section Diacritics
...( ARABIC LETTER FEH WITH DOT MOVED BELOW (ڢ) )...
May be add the unicode codepoint U+06A2 for this letter.

Other comments:
According to the notation "white circle (○) denotes a character that is auxiliary for that language. An X mark (✕) means the character is not used for that language", I'm confused with some x and some o :

ARABIC LETTER TCHEH, PEH, JEH and others are marked o. Should be x. Not used in Arabic.
Arabic Maddah, Hamza above, Hamza bellow ... are marked x. Should be o or dark bullet.
So are punctuation and symbols
« » ÷ x ARE used in Arabic.

Hi,

Thanks for catching the typos. Sent the commits for fixing them.

Other people have also found the language symbols in the table confusing. So, I’m creating a new issue (#52) for remembering to change them.

About the missing characters, there’s already an ongoing discussion in issue #49. I added your note there.

Thanks for the review.
