I got an email that contains in their name these rare symbols: 영웅재중 (I believe
these are letters japanese or chinese ). So when I try to visualize this email,
KMail becomes very very slow and seems to hangs some seconds, but after it
returns to the normality.

Here a screenshot of this email:

Also, the same behaviour occurs on Konqueror

Reproducible: Always

Steps to Reproduce:
Get an email with these "rare symbols"

Try out to read it

Actual Results:  
KMail becomes very slow and seems to hangs some seconds, after ir returns to
the normality

Expected Results:  
KMail should have their normal performance when these, rare symbols, are in a
email

OS: Linux (i686) release 2.6.34-ARCH
Compiler: gcc
