Daniel Brownell commented on PDFBOX-2665:
-----------------------------------------
I'm not too sure what the API should do, but all of the smart ways I've seen on
Stackoverflow of formatting text use a technique of judging the width of a Font
rendered String, by multiplying the getStringWidth() by a factor.
What I'd ideally like is for Type 1 fonts not to suck as much. If I have to
deal with width estimation, I'll need a hashmap, to convert my Strings before
they reach PDFBox.
For some reason I couldn't get \u0000 and \u0096 mapping, perhaps because
they're too crazy for Java. I can't get a String to print out at all if it has
a null character. I will take a look when I get back to work on Wednesday and
let you know. It's some obvious bug but it might be a pdfbox issue yet.
I think there should be a better way than whatever I'm doing, mapping Strings,
and it should be a default implementation option, since I'd think it would be
pretty common to deal with special characters and PDF fonts. Like almost an
ability to subclass the PdType1Fonts to add a default to the glyph map, so that
I don't have to deal with exceptions.
