Please describe this problem in detail:

I am receiving this message in my SMF forum error log:

http://www.redrancor.com/index.php?frontpage;p=20
2: mb_convert_encoding() [<a 
href='function.mb-convert-encoding'>function.mb-convert-encoding</a>]: Illegal 
character encoding specified

File: /home/content/03/6267203/html/Sources/Subs-PrettyUrls.php
Line: 77 

I am able to navigate to the page successfully, but I would like to find a 
resolution to the error--or at least determine why the problem is occurring.

What version of the mod, and what version of SMF are you using?

SMF 2.0 RC4, PrettyURLS 1.0RC5.1, and (in case it matters) TinyPortal 1.103

What other mods do you have installed?

TinyPortal 1.103
Bad Behavior Mod 1.4.4
Aeva Media 1.4c
Google Analytics Code 1.3

Please provide any additional information below.

I test-loaded the pages and they load successfully but very slowly because of 
the error.  It has only occurred for the three URL's I linked above (so far) 
and I tried navigating to p=90, etc. to try and reproduce the error but could 
not.

Thanks in advance for anyone taking the time to look into this, it is very much 
appreciated.
