you can get font from your computer. control pannel --> fonts
copy to the font you want to a new folder and rename it as myfont.ttf

from here /tpa/preset/system/fonts/ you will find a file called fonts.xml

here is the XML code (you can use notepad to save it as fonts.xml)

<xml>

<engine cache_size="393216" default="yes">

<font style="sans-serif" weight="normal">/tpa/user/other/myfont.ttf</font>

</engine>


<engine cache_size="183296" default="no">

<font style="sans-serif" weight="bold" >/tpa/user/other/myfont.ttf</font>

<font style="sans-serif" weight="italic">/tpa/user/other/myfont.ttf</font>

<font style="sans-serif" eight="bold-italic">/tpa/user/other/myfont.ttf</font>

</engine>

</xml>
(you can modify this xml by yourself. the "bold"italic"italic bold" no need be all the same files)
then use FAR (or other tool) to upload this .xml file to /tpa/preset/system/fonts/

and upload myfont.ttf to /tpa/user/other/

(Font Calibri is recommended for k610) :)
