I am seriously in trouble, I did not know this before my purchase!
Please help coffee cup or take some long-black coffee to write better program for us

I can type Persian, But then it turns to question mark when I preview or view in code tab.
Please view this demo:

This input language issue has already been covered in other (very recent) forum posts.

As far as your purchase; CoffeeCup offers 30-day trial versions of all their products which allows prospective buyers to see if the software will work for them or not. If it doesn't do what you want, I am surprised you didn't find this out before paying for it.

Dave.

Dave. As I am not writing in Persian all the time, but off and on I do so, I tried actually in Visual Editor mode and typed few words as I could write in then I did not bother to preview it where in same time something crossed my mind and carried me away.

Anyway, I am not regret at all and I just hope coffee-cup stuff will take some more long black coffee to write something for this for us to able write 100% Unicode characters.

Might CC website font help put in this instance?

My thoughts exactly David. Mansour that could be a temporary answer to your problems...

Website font only changes the look of the text that is present, so it would still just show question marks.

It does? I don't know how it works but guessed you could use any font you wanted and display it regardless of the rendering engine. I guess I guessed wrong...

I think we are kind of both right here, if I type in something in say Cyrillic font and neither the editor or browser understand it I will get question marks, but if I type in using the standard alphabet and use Webfont to change it to Cyrillic than it should work, and since the pages Mansour intends are to have a mix of standard and Persian text it should work, a quick jot to the free trial version should glean out the answer.

Worth a try

With that approach, visitors whose clients don't support sIFR, such as iPhones or those without flash installed, will see something like the following site. Make sure you view it with a non-IE browser. I believe IE automatically downloads and installs the required font... http://gujaratsamachar.com/

Without the required font, the page looks like gibberish. This would also be much more than sIFR was intended for, which is just for small font accents here and there rather than a page's entire content

UTF-8 could have been used on this page, making the need for font installation unnecessary. Though in this case I will admit the required font looks nicer than the unicode fonts I have, it also requires a custom keyboard map, which will likely differ from the key-map used by someone used to unicode.
