[9fans] p9p acme startup fonts.

[erik quanstrom]

i modified acme to not use /lib/font and to try $font
(like 9term) for p9p:

Acme's default font is variable-width, but $font is fixed-width.
You may prefer a fixed-width default font, but others do not.

Also, the /lib/font/bit paths are fine - libdraw will cope.

i didn't know most people set $font to a fixed-width font. i've been using a
variable-width $font for a long time:

; echo $font
/home/quanstro/plan9/font/code2000/code2000.14.font

(code2000 provides much better unicode coverage than pelm. and is
readable in smaller sizes.)

i haven't had any difficulties doing this. most programs that absolutely
need a fixed-width font do not play nicely with 9term because they also
use cursor addressing. the major exception being "cal".

i suppose the way to correct this $font abuse would be to use "font", "fixedfont",
and "varfont" environment variables. 

doesn't quite feel right, though.

The problem with Code2000 is that it's designer doesn't know the
languages he's making the glyphs for. As a consequence, many glyphs
are just "wrong".

For example:
http://www.travelphrases.info/gallery/samples/BitstreamCyberbit__Japanese.gif
http://www.travelphrases.info/gallery/samples/Code2000__Japanese.gif
(see the first (left) glyph in the bottom line)

Or:
http://www.travelphrases.info/gallery/samples/ArialUnicodeMS__GreekPoly.gif
http://www.travelphrases.info/gallery/samples/Code2000__GreekPoly.gif
(also the first character in the bottom line)

what's wrong with the greek?

i do not have microsoft unicode fonts converted for use with p9p,
but i do have cyberbit. all the greek glyphs that appeared in
side-by-side terminals 

; font = $PLAN9/font/code2000/code2000.16.font 9term &
; font = $PLAN9/font/cyberbit/code2000.16.font 9term &

for each with this script

; grep GREEK UnicodeData.txt | awk -F';' 'length($1)==4 {printf("\\u%s	%s	%s\n", $1, $1, $2);}' | uconv

were the same. cyberbit was missing all the combined greek characters, though.
code 2000 has them.

could you send me some of the codepoints from the 
japanese example so i can check those, too?

are there any unicode fonts out there that offer full coverage from \u0000
to \uffff that aren't super ugly?

code2000 at least has allmost all symbols and arrows. and looks okay.

(uconv just converts \uXXXX → unicode codepoint XXXX.)

sorry to bother the list but i'm getting 451 errors from sneakemail.com:

-Queue ID- --Size-- ----Arrival Time---- -Sender/Recipient-------

                                         XXX@sneakemail.com

anyway, a couple of people have asked so maybe 
it's not a complete waste of bandwidth.

i used ttftosubf (http://pages.cpsc.ucalgary.ca/~mirtchov/p9/freetype/) to
convert code2000 (http://home.att.net/~jameskass/CODE2000.ZIP). however,
since it's shareware, i'll email anybody a copy of my $PLAN9/font/code2000
but please be able to accept a 20M email if you ask ☺.
