Description Subrahmanyan K.H. 2006-08-20 22:37:39 UTC

Hi,
	We have a Unicode CJK font, when we use that in PostScript with 
selectfont and try to view the Postscript document with GhostScrpt, we are 
getting the 'rangecheck' error. This is happening both on windows and unix, in 
gs 8.54 and 8.53.

Thanks
Subbu.

PostScript document with CJK font reference

PostScript document, which refers to the CJK font and has the problem.

Error text file

This is the error we get when we try to view the PS file with GS.

Comment 3 Subrahmanyan K.H. 2006-08-20 22:54:55 UTC

Initially we had only one font (amwt_f1.ttf). To improve the PS transformation, 
we requested our font vendor to split the font.
They split the font into 2 subsets, one with all CJK characters and one with 
non-CJK characters. Now with the CJK font we are getting the 'rangecheck' error 
while loading the font. 
Please provide the FTP site details, so that I can upload the font.

I've modified the test file to use AMWT_F1_CJK_test.TTF and the file fails
with the same error message, so I do not require the 'test2' font.

The problem was an 'off by one' condition in the "get_from_stringarray" procedure.
