problem with RenderObjects - Fonts with CE signs

Dears,

I have a big problem with saving text as DrawObject (type=100)
using Font with CE signs f.e. Arial signs: ąśćół...
on preview by AddDrawObject all is ok but after rendering the objects
(by COMPDF_RenderDrawobjects) the signs are not correct

How can I add text on pdf included Font CE signs

pls help

Do You have any idea how can I put some text on pdf with CE signs and in any way store it?
I try solve my problem by creating an image with text
but i receive not needed background

...so maybe can You add in update set of 16 signs:
ę Ę ó Ó ą Ą ś Ś ł Ł ż Ż ź Ź ć Ć
f.e. Arial font and it will not be too complicated
but it will be very helpfull for me :lol:

in summary
THE TOOL IS EXCELLENT SO I INPLEMENTED IT DEELPY IN MY SOFTWARE PROJECT as WPTOOLS Premium too
but the mising CE signs in PDFVIEW now seems to be a small trouble...
