matlab - Ghostscript postscript pswrite is encoding text -

why ghostscript pswrite encoding text in output? consider next mwe:

%!ps-adobe-3.0 %%title: mwe.ps %%pages: 001 %%boundingbox: 0 0 595 842 %%endcomments %%page: 1 1 %%pageboundingbox: 0 0 595 842 0 0 1 setrgbcolor 0 0 595 842 rectfill 1 0 0 setrgbcolor 247 371 100 100 rectfill /times-roman findfont 72 scalefont setfont newpath 247 300 moveto (chris) show showpage

saving mwe file , viewing in gsview display bluish page reddish square , name underneath. run file through ghostscript 9.06 next command line:

"c:\program files\gs\gs9.06\bin\gswin64c.exe" ^ -dsafer -dbatch -dnopause ^ -sdevice=pswrite -spapersize=a4 -r72 -soutputfile=mwe_gs.ps mwe.ps

see ghostscript output below. can please explain happening here. whilst 2 rectfill commands still apparent, text (chris) has been encoded , no longer distinguishable.

is there alternative postscript device retain text please?

note: might seem odd activity i'm exploring thought of using ghostscript 'clean up' postscript output matlab application..

the 'text' has been converted images, not vector paths. serious limitation of pswrite device, , 1 of reasons deprecated, should utilize ps2write device instead. reason pswrite device still included @ epswrite uses (which why pswrite , epswrite output looks same). @ point there eps2write device , pswrite binned.

ps2write output is, default, compressed. if want uncompressed output, utilize -dcompresspages=false switch on command line.

if want location of text might consider txtwrite device. default implementation of creates plain text representation of input, can have output faked xml instead includes things origin of text.

Accessing MATLAB's unicode strings from C -

Accessing MATLAB's unicode strings from C - how can access underlying unicode info of matlab strings through matlab engine or mex c interfaces? here's example. let's set unicode characters in utf-8 encoded file test.txt, read as fid=fopen('test.txt','r','l','utf-8'); s=fscanf(fid, '%s') in matlab. now if first feature('defaultcharacterset', 'utf-8') , c engevalstring(ep, "s") , output text file utf-8. proves matlab stores unicode internally. if mxarraytostring(enggetvariable(ep, "s")) , unicode2native(s, 'latin-1') give me in matlab: non-latin-1 characters replaced character code 26. need getting access underlying unicode info c string in unicode format (utf-8, utf-16, etc.), , preserving non-latin-1 characters. is possible? my platform os x, matlab r2012b. addendum: documentation explicitly states "[mxarraytostring()] supports multibyte encoded characters...
