Re: ps2raster error abot Chinese characters

Thank you, Lei Yang and Dongdong Tian, for your extensive bug reporting and tracing of a bug in GMT5.

You were absolutely right that the option for ghostscript "-sFONTPATH=C:\Windows\Fonts" was not used when determining the BoundingBox first (when the -A option is used). So indeed, this resulted in the failure.

I’ve updated the code so that the fix is now available in the SVN version.

A related issue: maybe the option "-sFONTPATH=C:\Windows\Fonts” should be implicit when on a Windows system. I’ll let it to the GMT users and developers with Windows knowledge to comment on this.

If you think this is useful or essential, please add a “new issue” on the gmtrac web page. That’s the best place for tracking bugs and user requests:

Best regards,
Remko

While I don't know how  this all works, we have a GMT example that shows the use of Cyrillic  alphabet (example 31) which provides its own files for those  characters.  Perhaps studying that example can give you some hints.
