[Opera-Linux] Can't get a proper quote mark

[Bruce Bales]

Hello, All,

I'm using Opera 9.23 and one internet page I am trying to read seems 
to have some punctuation marks which can't be properly rendered.  The 
partial sentence " words like “Man” and “parade”  in the"
probably was supposed to be 'words like "Man" and "parade" in the.'

The single quote is similarly messed up as in  The young man’s 
parents ....

I have tried to find something in the preferences that might be 
responsible, with no success.

Can anyone steer me to a solution?

Thanks in advance,
bruce
