Hello again,
I did some research on news portal source code. I think the function:
HTML_ijoomla_news::unhtmlentities($str)and HTML_ijoomla_news::cutstring_html ($str) are not working correctly for my case.

I want to make sure all following characters, if exist, will be shown correctly:
-----------------------------
á,à,ả,ã,ạ,a,Á,À,Ả,Ã,Ạ,A

ó,ò,ỏ,õ,ọ,o,ú,ù,ủ,ũ,ụ,u,Ó,Ò,Ỏ,Õ,Ọ,O,Ú,Ù,Ủ,Ũ,Ụ,U

é,è,ẻ,ẽ,ẹ,e,É,È,Ẻ,Ẽ,Ẹ,E

ó,ò,ỏ,õ,ọ,o,Ó,Ò,Ỏ,Õ,Ọ,O

ấ,ầ,ẩ,ẫ,ậ,â,Ấ,Ầ,Ẩ,Ẫ,Ậ,Â

ớ,ờ,ở,ỡ,ợ,ơ,ứ,ừ,ử,ữ,ự,ư,Ớ,Ờ,Ở,Ỡ,Ợ,Ơ,Ứ,Ừ,Ử,Ữ,Ự,Ư

ắ,ằ,ẳ,ẵ,ặ,ă,Ắ,Ằ,Ẳ,Ẵ,Ặ,Ă

ế,ề,ể,ễ,ệ,ê,Ế,Ề,Ể,Ễ,Ệ,Ê

ố,ồ,ổ,ỗ,ộ,ô,Ố,Ồ,Ổ,Ỗ,Ộ,Ô
--------------------------
Could news portal's developers help me on this?

Look forward to hearing from you.
