4e4d1a5cd5 Convert "block", "lfblock" and "rtblock" to mosaic graphics. 
In Unicode, these will be unified with 6-cell mosaic graphics, so we
need to use the mosaic graphics system for them.

6bdb83305e A few interesting characters from U+1FBxx. 
That's the forthcoming "Graphics for Legacy Computing" block that will
finally have an official encoding of teletext mosaic graphics.

c78b95f6f0 Add Cyrillic letters necessary for Serbian. 
That's dje, je, lje, nje, tshe, and dzhe.  Because I got an email from
Serbian Wikipedia.

ae3be652a3 Bump version number to 002.000. 
I can't think of anything else I need to do for it.

829128680a Slight change to U+241B SYMBOL FOR ESCAPE. 
The "C" is now more obviously a "C" and not a "(".

480682f5f8 Rationalise widths of Bedstead variants. 
They are all now sensible fractions of the standard width.

Extra Condensed has changed from 62/100 to 5/8.
Condensed has changed from 76/100 to 3/4.
Semi Condensed has changed from 88/100 to 7/8.
Extended has changed from 124/100 to 5/4.

This makes rather a lot of dimensions non-integer, but the only
significant ones are the "palt" width adjustments, and I think that's
an acceptable tradeoff for making the standard widths more sensible.

7473a75d39 Turn XPIX into a double. 2018-04-06 23:26:33 +01:00

d655ebfcb1 Convert a bunch of printfs to %g. 
Along with casting arguments to (double), obviously.

b86aa20400 When printfing dimensions, cast them to the right type first. 
That way, if floating-point numbers turn up, they won't get
interpreted as ints and cause a horrid mess.

8c6f94dd3c Move .notdef to the end of the list with the other unencoded glyphs. 2018-04-04 22:16:01 +01:00

1006cc012b Consistently put a blank line before each Unicode block heading. 2018-04-04 22:15:27 +01:00

463eeb6462 Add Marnanel Thurman to list of authors and update dates. 2018-04-04 22:14:31 +01:00

5d4e9baeec Add the Shavian alphabet to Bedstead. 2018-04-04 22:10:47 +01:00

6a4238d2d2 A few more forms of transport. 
Inspired by seeing U+1F69A DELIVERY TRUCK in the subject line of an
email, here's a glyph for that and also U+1F680 ROCKET and U+1F682
STEAM LOCOMOTIVE.

543f43a2f3 Move stroke on dotless j with stroke glyphs down by one pixel. 
This makes them match the lower-case "f" of which these characters
were originally turned versions, and also makes U+0284 LATIN SMALL
LETTER DOTLESS J WITH STROKE AND HOOK more visually distinct from
U+0192 LATIN SMALL LETTER F WITH HOOK.

04bc584c97 Slight tweak to "AE": move crossbar of "A" part down 1 pixel. 
That puts it in the same place as in the "A" proper, and aligns with
the advice here:

https://medium.com/@frodefrodefrode/designing-the-letter-%C3%A6-862cffbe22b

"The crossbars are not usually aligned in typographic typefaces ..."

6120176259 Complete the set of circled and squared plus, minus, and dot. 2017-11-26 23:33:06 +00:00

a287174507 Add a couple of upside-down characters. 2017-11-26 23:26:58 +00:00
Ben Harris
049d92d5f2 Add prime and double-prime glyphs. 
Not the prettiest, but they're visually distinct from apostrophes and
accents.

f1f7599854 Add therefore and because symbols. 2017-11-26 15:48:33 +00:00

7174e3015b Add white left and right triangles. 2017-11-26 15:28:53 +00:00

be454b1d55 Add gratuitous cube root and fourth root symbols. 2017-11-26 14:42:34 +00:00

ee8a8325ad Add assorted mathematical vertical lines. 2017-11-26 13:54:45 +00:00

ffc5a9de9c Add mathematical ellipsis characters. 2017-11-26 13:42:13 +00:00

64dd2d9a28 Two-level brace and summation characters. 
The braces are a compromise, since each glyph has to be usable as both
the top and bottom half of a brace.

fe017bcbc3 Be consistent in capitalisation of block heading comments. 
I use sentence case for these where the Unicode standard uses title
case.
 2017-11-26 12:02:59 +00:00
Ben Harris
f1bac5326e Add the various long bracket components. 
All are derived simply by lengthening the vertical parts of the
standard glyphs.

fcd5771e00 New, better invsmileface glyph. 2017-11-26 10:28:55 +00:00

c33fc255ec New unhappy face glyph. 
It was the only missing face in the BMP.

5723961091 U+2126 OHM SIGN 2017-11-24 22:20:25 +00:00

88348059ee Add U+2044, "fraction". 
I think that completes StandardEncoding.
 2017-11-24 22:04:13 +00:00

f09162f992 Assorted accents from StandardEncoding. 2017-11-24 22:00:40 +00:00
Ben Harris
c3842c2963 Add "fi" and "fl" ligatures. 
Not actually enabled as ligatures, since that would be silly, but some
character sets want them as presentation forms.
 2017-11-24 21:38:42 +00:00
Ben Harris
08e561d2e3 Add capital schwa glyph. 
I keep seeing it in Commons filenames written in Azerbaijani.
 2017-11-21 22:50:02 +00:00
Ben Harris
458304cb30 Add partialdiff glyph. 
It's part of Mac Roman, and probably some other interesting encodings.
 2017-11-21 22:17:37 +00:00
Ben Harris
fc04f77124 Add the tab-key glyph. 
Because it's just about possible.
 2017-11-21 11:43:30 +00:00

f26a79bb56 Subset and superset symbols. 
The proper subset symbol is only slightly different from lower-case C,
but I think that's inevitable.
 2017-11-21 11:28:15 +00:00

c9d168e234 Large mathematical operators: summation, product, and integral. 
All of these span the full height of the character cell, since that way 
they'll work equally badly with subscripts and superscripts.
 2017-11-21 11:21:35 +00:00

75e04065fb A tolerable perthousand sign. 
I've made so many bad attempts at this character that this feels like
a win.  Also, it's an annoyingly common character in character sets
I'd like to cover.

6270d56611 Set the "H" flag on all glyphs in SFD files. 
This turns out to  be all it takes to get  FontForge to autohint fonts
on generation.  FontForge's autohinter  isn't perfect, but it's pretty
good and certainly better than anything else I've got.

63b418811a A scattering of additional characters from Latin Extended-A. 2017-08-09 23:25:04 +01:00

7864d4d1c8 Clip character names to boxes in glyph complement. 
Ideally, I'd do something more elegant with over-long glyph names, but
at least keeping them in the boxes doesn't look terrible.
 2017-08-09 22:23:48 +01:00
Ben Harris
6a099893dd Add U+0149, "napostrophe". 
That's the only character that Font Library says is missing for
supporting Afrikaans, so I may as well implement it even if Unicode
does say its use is strongly discouraged.

051d1c662c Emit open contours starting at the beginning. 
Before this change, emit_path() would emit contours starting at
whichever point was earliest in the points array.  That was fine for
closed contours, but it meant the open contours tended to be emitted
in multiple parts.  Now it first searches for start points of open
contours and emits those, and then does what it used to do to emit the
remaining (closed) ones.  This has no effect (other than to slow
things down a bit) for fully-closed paths like those in outline
versions of Bedstead, but it makes the stroked ones much cleaner.  Now
a contour can only end at a tip or at a 3-way junction.

82d22a5289 It's the future: C has a boolean type. 2017-08-08 22:26:58 +01:00

bc10355aa5 Extract code to emit a single contour from emit_path(). 
I want to make emit_path() more complex, so pulling out this obvious
unit seems wise.
