I think I'm a bit closer in understanding the issue.  Thanx to Marcel's
PDF creations (thank you Marcel, very appreciated), I've had a file for
comparison.  As I suspected, there is an "encoding"-problem or maybe
rather an "encoding-interpretation"-problem.  When creating a PDF
through PostScript, the issue becomes "ironed" out, so this issue only
arises when creating PDFs directly (like on-demand, streaming PDF's on
the internet). My guess is that when Evince encounters an encoding that
hasn't been implemented or can't be read, it assumes the encoding should
be "Identity-H" (see the following links)

http://www.talkgraphics.com/showthread.php?33648-What-is-identity-H

Where as xPDF and Adobe Reader, either has the encoding implemented or assumes 
the encoding is "Custom", but display it as "Ansi".  Evince displays it as 
"Identity-H" an tries to draw the text/letters as some weird font or attached 
vector-graphics image.  So there is probably two issues ...one is the PDF 
creation, which is not always done "beautifully" ...two is the rendering, which 
doesn't always account for PDF-format discrepancies.
But either way, I would still recommend that the interpretation of 
discrepancies in Evince should be the same as Adobe Reader and xpdf. (even 
though I'm a believer of creating data-files according to their definition as 
agreed)

For further testing, you would proberly need to create a PDF that uses
the non-embedded fonts AND is created directly, without using any form
of PostScript. (I'll would suggest PDFLib - www.pdflib.com)
