Dear Sir,
Each time I apply new Arabic theme I get invalid char. "??????????" instead of the original one. My blog is running on wordpress. My problem began from 3-5 months earlier and I thought that the problem is caused by me. I tried many times to solve it but not succeed. I asked the support forum of wordpress and I got the answer that it may be from the host and told me that they may not support Arabic language.
So please kindly, Can I find a solution to my problem? I attached a screen-shot to my problem.
