i wanted to make the captcha in hebrew so at least spammers that dont read hebrew cannot write in.
so i've added
RadCaptcha1.CaptchaImage.TextChars = Telerik.Web.UI.CaptchaPossibleChars.CustomCharSet;
and i've got nice hebrew captcha
but when i tried to enter what i've seem in the image it told me that i written the wrong code.
it showed "אבגדה"
so i've entered "א" "ב" "ג" ד" ה"
and then i figured that i needed to enter the letters from the left to right
"ה" ד" "ג" "ב" "א"
and it passed just fine.
can you add an option to parse the text in reverse that way you get full RTL support.
