It looks like there's some problem in pfaedit, the font editor I use. (If you 
know of any other font editor I could try please tell me, I couldn't find 
anything else that handles both type1 and truetype).

If I open the cmsy font from bakoma, pfaedit converts it to its internal 
postscript format. Saving as truetype again is basically exporting from 
pfaedit's pov. Now, if I export the cmsy font agin, _making no changes_, the 
newly created font won't provide the 'broken' characters such as /leq. If I 
open the new font in pfaedit again, though, the characters are still there 
and look perfectly ok, so I don't really know what the problem is. I'm going 
to mail the pfaedit-devel list asking for help.

Well, that, and they have patches to disable *any* "old-style" X fonts
for Qt/GTK+ apps.

Ah yes, I forgot the original problem - fontconfig won't select/return the

This isn't a full list :)

Attached is a hacked-up lyx document with the symbols from lib/symbols/
It should load into 1.3.x, just ignore the warning

The problematic ones are :

\kappa
\spadesuit
\leq / \le
\upuparrows
\circleddash
\nleqq
\backepsilon

These ones really need to be fixed. It would also be nice if we could
add the ones currently in ERT from wasy, at some point.

Hmm. Looking at it, it provides the mapping of the orig bluesky type1 fonts, 
not that of the bakoma ones. Why can't lyx use that and the bluesky fonts 
natively?...

Anyway I decided I was beaten on the path of trying to automagically convert 
the bluesky fonts to ttf ones that look like bakoma's. And having already 
spent about 20 hours on that, I decided I could spare another hour or two 
doing the same thing by hand.
So I've taken the bakoma fonts, removed all glyphs, and copied over the 
bluesky glyphs, changing the font properties as needed. In the end nothing 
remains of the bakoma version but the way the characters are arranged, which 
is what we want. This should be ok wrt bakoma's copyright (IANAL)...

This is still WIP due to issue #2 below, but since I'm prolly not going to do 
anything more with this today, I wanted to update the list. The fonts are at 
http://cvs.gentoo.org/~danarmak/fonts-v2.tar.bz2 - testing appreciated (last 
time it took about 10 minutes for the big problems to be found, but this time 
I've tried to do better testing).

Known issues:

1. Quality loss: tolerable for on-screen editing (imo at least).
Details: I converted the glyphs from postscript to truetype. That's apparently 
a lossy conversion (unlike the other way around) - which I only found out 
when it was too late. I converted to opentype (which has the same spline 
format as type1) which recovered most of the quality (but is still worse than 
the printed bluesky). So it looks worse than the bakoma stuff (due to the 
lossy conversion I suppose), but tolerable for editing (as long as you don't 
write too many formulas :-). Probably something could be done if I started 
all over again... (The font is also smaller than the bakoma one - try using a 
bigger fontsize. Can we get a separate fontsize setting for the mathed?)

Also, the hinting went mad for some reason and most chars were over-hinted 
into smudged oblivion. I told pfaedit to remove all hints/instructions and 
autohint. Now it's usable - but I probably lost some of the custom hinting 
instructions that make bluesky look good (in particular most of the Latin 
alphabet in cmr10 had custom stuff). Again, tolerable (for me) since this is 
just for editing.

2. Some chars won't draw - lyx displays a square instead. This is the major 
thing left to be fixed.

Looking at the kappa char for example (from cmmi10), every other char in the 
font draws OK and AFAICS there's absolutely no difference between it and the 
bakoma one, in the kappa char's properties or otherwise. I really don't know 
what to do about this kappa problem...

A full list of the problematic chars:
\leq \kappa \circleddash \nleqq \upuparrows

3. At some point the characters lost their names and got the names of the 
unicode characters at their encoding positions instead. This doesn't affect 
lyx which draws by encoding value not name (I wish I'd known that sooner), 
but it makes further editing of the fonts icky. If there's sufficiently good 
reason, I can create them again, and hopefully keep the names that time.

4. There are still no eufm10 and wasy10 fonts, because there aren't such 
bakoma fonts (maybe they are in the bigger bakoma collection on ctan though). 
However AFAICS lyx doesn't need/use these fonts anywhere? I tested all the 
characters listed in the matheditor float and they were present without these 
fonts (except for the ones from issue 2 above, and they got drawn as squares 
and not written in red, so they must be from the existing fonts as well).

Can you check if things work if you set LANG=ru_RU ? I suspect they may
still break, but it would be nice to check.

Sorry, my mistake. My scripts actually told pfaedit to change every 
character's name to match its new unicode value! So most characters now have 
wrong names...

Problem is, if I tell pfaedit not to change the names (call from script 
SetUnicodeValue(value, 0) ) it segfaults... Don't know why, or how to go 
around it, yet...

I looked at kappa as an example. It:
1) exists in cmmi10 (both bakoma and bluesky-derived versions). So apparently 
lyx isn't using that font here. (BTW I'd really appreciate an explanation of 
what characters it takes from what font, since most of them are present in 
several.)
2) exists in bakoma msbm10 as "kappa" at unicode address 007b. It also exists 
in my bluesky-derived font at 007b, but isn't called "kappa". Rather, it's 
called "braceleft", which is the unicode char that really owns location 007b. 
How that name got there, I've no idea, since it is called "kappa" in the 
original bluesky type1 font, so either my generating scripts or pfaedit 
itself are at fault...

I'll try to fix this - there's a whole bunch of characters around kappa in 
msbm10 that have the wrong names (the names of the unicode chars that should 
be at their address). Meanwhile a quick explanation of when lyx uses unicode 
values, and when it uses character names, would be much appreciated.

If you can tell me in which fonts these are supposed to be, I can add them 
(assuming I can find them somewhere in the bleusky or other texmf type1 
fonts). Or I could just check all the bakoma fonts to see which have these... 
(Assuming the character names are also 'kappa', 'upuparrows' etc?)

For the latter two I would need to know the "unicode" values to use as well 
(what does lyx expect them to be?)

I say "unicode", because the values used by bakoma aren't the real unicode 
values for these chars - they are some weird custom and (to me) meaningless 
values, which is why lyx can't use any truly unicode font that provides the 
necessary symbols. It took me two days to realize that, after which I just 
spent several hours scripting pfaedit to grab the character name --> 
'unicode' value mappings from the bakoma fonts, and rearranging the bluesky 
fonts to match.

That's because bakoma doesn't have eufm10 either (nor wasy10). I intentionally 
didn't put in anything that doesn't exist in the bakoma package, because I 
wouldn't know what unicode values to give the chars.

I had a problem with the following symbols: \kappa, \upuparrows, 
\backepsilon, \nleqq, \backepsilon and \circleddash.
They appear as a square (the latter two also appear as squares when using
the bakoma fonts, so it is possible that the problem is in lib/symbols).
I'll investigate later.
Also, eufm10.ttf is missing

Hello everyone,

Sorry for shouting SOLVED like that, but I've been working on this for the 
last three days, and solved the problem through sheer stubbornness, because I 
started out with zero knowledge... So now I'm really happy :-)

Someone please fetch and test http://cvs.gentoo.org/~danarmak/fonts.tar.bz2 . 
These are modified bluesky fonts. Use as a replacement to the bakoma ones (no 
change needed to lyx code).
Just put the fonts somewhere under /usr/share/fonts, run fc-cache as root and 
as user, run lyx with a qt3.1 interface (that uses fontconfig+xft2) and see 
if the matheditor's formulas show the right characters.

Someone please confirm that it works (and I wonder about the xforms frontend, 
since it doesn't use fontconfig afaik...), and if it does work, I'll provide 
details about it if anyone wants them. If it doesn't...
