Problem with render fonts

Hello everybody.

Sorry my english please, it is not native for me.

I faced a problem while using Magick++. I wrote small application using 
Magick++. One of tasks - render users messages. User could type message 
and my application render it on his photo using choosed font 
(family,size..etc). The problem is: on sentos 5.2 64bit it cuts spaces. 
It render fonts and all is almost ok, expect spaces. For example, 
message was "hello world". It render just "helloworld" without any 
spaces. On another machine (with another linux version and 32bit ) all 
is ok. I updated ImageMagick to 6.4.2 on both machines and result is the 
same. I suppose problem could be in font library (i'm not sure, sorry if 
stupid suppose). I want try to update fonts library, if it is possible. 
Could you say me what library Magick++ use for render fonts? (if it use 
any, sure).


Thank you,
Andrey.
