Subject Re: IllegalArgumentException when using PDType1Font.HELVETICA
Date Thu, 28 May 2015 10:38:09 GMT
Thanks for explaining!

Using a Helvetica.ttf file I was able to solve the error about 8-bit code
points. Apparently the PDType1Font.HELVETICA does not include all
characters that are supported by Helvectica.
The new line is now handled before calling showText().
