SVG2PDF Some characters not recognised when transforming to PDF

Hi there,

 

I have a Java Stored Procedure in Oracle that converts a CLOB feed of
SVG based XML into a PDF file and stores it as a BFILE.

The following code works. 

 

Code:

*********************

 

I am quite baffled as to how I resolve this.

I tried naming standard fonts e.g. Courier, Arial Times Helvitica. But
it came down to the same issue each time, it is only when the character
4 or x is displayed as text that the error occurs.

 

Any ideas would be appreciated.
