Can i put an SSID with arabic letters or no?
What you probably need is support for unicode characters.
From my research it seems that the specs allow it.
Quoting IEEE Std 802.11 Part 11
(you can download it here:
http://standards.ieee.org/getieee802/download/802.11-2012.pdf
8.4.2.2 SSID element
The SSID element indicates the identity of an ESS or IBSS. See Figure 8-82.
The length of the SSID field is between 0 and 32 octets. A SSID field of length 0 is used within Probe
Request management frames to indicate the wildcard SSID. The wildcard SSID is also used in Beacon and
Probe Response frames transmitted by mesh STAs.
When the UTF-8 SSID subfield of the Extended Capabilities element is equal to 1 in the frame that includes
the SSID element, the SSID is interpreted using UTF-8 encoding.
Now only 32 bits are reserved for the SSID, so if you use UTF-8 (which is part of the unicode spec), you will be allowed much less characters in the SSID name.
It also seems that it has been implemented in some routers:

I didn't design or write code for your router so I don't know if it is possible on that particular device. Apparently not, and it would be the case with many (especially cheaper) routers, I guess, because it's probably much simpler and easier for the maker not to allow it.
So all you need is find a router that supports that.
I hope you tried researching it yourself first. If not please do next time.
PS: If you find a router that supports unicode, you might still have problems with some devices connecting to it (mobile phones for examples) which may not support unicode SSIDs.
