hello
I'm learning a bit about fonts and while the following link did help
to some extent,
http://mindprod.com/jgloss/font.html
there are still questions bugging me about the subject!
Again, I apologize for so many questions, but I think other thread
makers would not appreciate it much if threads on first page were all
made by little me ( I realize all bunch of questions in one thread may
turn off potential helpers and thus may not give long and thorough
explanations on all individual questions asked )
1) Since there are five logical fonts in java, then that would suggest
that not all physical fonts can be mapped to single logical font. So
what property makes physical fonts fall into one of five categories,
thus why not have just one logical category which could map to all
physical fonts?
2) I know java has build in physical fonts, but can logical fonts
themselves represent characters visually, or must they always be
mapped to physical fonts? Why?
3) I've read that logical fonts represent more characters than most
physical fonts do. Huh?! If logical fonts themselves can represent
characters, then why the need for mapping to physical fonts?
4) Can particular font support several encoding sets?
5) If answer is yes to the above question, then how do fonts relate to
character sets? For example:
Say we have a font that is able to display all ascii characters.
We also have two different 7 bit encodings EN_1 and EN_2. Both are
able to display all ascii characters. But they have different code
points for individual characters ( for example in EN_1 code point for
character A may be 65, while in EN_2 codepoint for A may be 100 ).
Is always creator ( programmer not god ) of this font the one which
enables support for both EN_1 and EN_2 encodings, or can this also be
done manually ( by manually I mean by local users who'd somehow map
individual glyph to particular codepoint )
thank you
