[RT 130041] Warn that fonts are not embedded by default

User searches for the word "embed" and finds only
Quote
       -noembed
            Disables embedding of the font file.

so assumes fonts are embedded by default.

Alas it turns out for cjkfonts no embedding is possible, which the user will only find out too late when he is already at the printing company...

Hmm. Some day I'll have to deep dive into the PDF::Builder code and see what makes CJK fonts so different from other (TTF/OTF) fonts, and why they can't be embedded. Ditto for 130040 (can't synthesize a font from CJK). That's assuming that it's not a simple oversight, and that the .data files are still a significant difference.

(Non-embedded looks great at home, no matter what browser, viewer, etc. but once you get to town... surprise surprise :-( ).

I also note that sometimes the (pdfcairo) embedded font version of a PDF is smaller than the non-embedded font version!
Code: [Select]

[pdfcairo is a tool to convert PDF to many graphics formats. apparently with -pdf it embeds fonts in a PDF.]

Documentation has been clarified on when and how font file embeds are done. Only ttfont does embedding (not cjkfont, nor the others). It is often possible (with recent vintage OTF files) to use ttfont instead of cjkfont to produce CJK text. In addition, a bug in handling CFF OTF and TTF files was fixed, where the font file was always embedded (yet unusable) even when -noembed=>1.

Closing. This is in release 3.016.
