We were able to resolve this- you were right- it was in the database- while parts were set correctly, we found that some were not. Now that it is all in the utf8 the comments are working. I also uninstalled it and reinstalled it. Between the two- it is now working. Yea!
I am also seeing the same issue. My visitors were posting comment in "Hindi" language and all I see is "??????". After reading this thread, I checked the jos_comment table and it was latin_swedish..." something.. So I changed the collation of the table to "utf8_general_ci" but I still see the same "?????" in the comments..
I think at least all t he jos_comment tables need to be changed to this "utf8_general_ci". Make sure that all the admin settings in joomla component for jos_comment are also set for your language. These steps worked for the Arabic. Other's here know more than I do- but these are my thoughts.
I have a problem with the romanian special character like ăîşţ . when I post a comment it shows ? character instead of the romanian special characters.
Also I have seen that in DEMO website you have the same problem.
Can you please tell me how to solve it ?
Thank's Daniel. The problem with the Demo on the site is probably with the charset wich is not set on UTF-8 and it's in latin .
I solved my issue. The problem was that I did not made the modification on the proper table . So , as you said , the problem was from CHARSET witch was "latin"...
