[mythtv-users] UTF-8 display problem in program guide with 0.21.0+fixes19961-0ubuntu8

[Clark Lee]

Dear All,

I am using the mythtv pre-compiled version 0.21.0+fixes19961-0ubuntu8 with Ubuntu 9.04.
The problem is that all UTF8 characters (in my case Chinese) is displayed as ?????? in the program guide.

It is really strange. I have made sure I have done the following:
1) change the mythconverg database to use utf8 as default character set;
change the default collation as utf8 as well;

2) change the program table title/subtitle feilds to utf8 as well;
change the default collation as utf8, too;

Now, if I access the database from any mysql client, I could see the program title/subtitle as displayed correct.
And, I have installed Chinese locale, both simplied and traditional Chinese. 

I could login to gnome with Chinese menus, and all display well.
I set the mythtv language setting to "Hanzi (Chinese)", program guide charater as first choice "Chinese" and the second as "English".

Menus is 'default'. The Chinese menu is displayed correctly; however, if I go to the program guide page, the program names/titles are all in ??????, except for some digital figures and english characters. 

What should I do? 
How the program guide language settings affect the display of program guide page? (I am puzzled here, because I think once UTF-8 is used, any character can be displayed correctly)

P.S. I used to use mythtv trunck code v0.21 and compile my self on Ubuntu 8.04, the program guide shows correctly once the database is correctly setup as above. 
Now to save time of compile, I switched to the pre-compiled version.

Thanks very much,

Clark
