Build Identifier: 20090920-1017

Non-ASCII characters are not encoded according to the Postscript specification if used with a standard Postscript font. With a non-standard font they are rendered correctly.

The problem seems to lie in the method org.eclipse.birt.report.engine.emitter.postscript.PostscriptWriter.applyIntrinsicFont(String, int, float, String), which does not take encoding into account.

For a standard (intrinsic) font it generates something like this:
/Helvetica 18.0 usefont
0.0 0.0 0.0 18.54 721.476 0.0 0.0 (abc זרו - sans serif) false drawstring

For a non-standard font the output is a font definition (I think) and an encoded text:
/Century 18.0 usefont
0.0 0.0 0.0 18.54 695.505 0.0 0.0 <004400450046000300a000a1006e000300100003002600480051005700580055005c> false drawstring


Reproducible: Always

Steps to Reproduce:
1. Create a simple report and add a label that contains non-ASCII charaters (e.g. "זרו") and use a standard font, e.g., sans-serif (which becomes Helvetica). Create another label in the same way, but with a non-standard font. An example is attached
2. Render the report as postscript
3. View or print the file. The non-ASCII characters are not rendered correctly with the standard font

This is caused by the incorrect font mapping of Sans-serif, which should be mapped to a true type font, otherwise, the non-ascii characters can't be displayed.
Standard fonts can't be used to display non-ascii characters.
It was fixed with bug 308780.
