I am creating a forum (based on phpbb2)where people will be allowed to post in 2 langauges: English and Greek. I want all posts in both languages to be readable at the same time. It seems to me that if i use the Greek encoding (iso-8859-7), posts writen in both Greek and English can be read at the same time.

Are there any common english characters that will not be able to display if i use the Greek encoding? Will there be any other problems if i do this?

Is there a better way to achieve what i want? (English and Greek posts can be on the same page)
