Do you want to say that we need an explicit definition of LM Math?

Just curious: how much information is missing/how much would would it
be if we would want to create a virtual math font by combining LM +
populating italic/bold/bold italic latin and greek math alphabets from
text font? Would that look horrible because of lack of information
about glyph metrics?


that is relatively easy: just make a lfg file that contains the 
specification (and choose some math font that suits)


my guess is that it will look bad in most cases

we might consider making a sort of generic partial math font (maybe even 
needs to be designed) that sort of fills in the usual bits and pieces 
(root signs, arrows etc) in a way that matches an average font


(we probably need a few weights then)

of course that would only work for not too fancy math

Re: [NTG-context] handling fonts with missing math

2011-09-28 Thread R. Ermers
Dear All,

In the mean time my general font problem subsists.

It seems that the gentium font is not loaded at all (see snippet from log 
file). I use the regular standalone installation, I have not changed anything. 
I use the standard typescript file. 

Note that my file processed normally, including the gentium font, until the 
last update. I currently use version 2011.05.18 18:04.

Do I have to change anything?

Regards,

Robert

Snippet 1 from log file:

2011-09-28 Thread R. Ermers
Thanks Luigi,

The option with simplefonts does not work either.

Please have a look at the snippets below. There it says that simplefonts is 
loaded.
There still is an issue with a math font.

I think the two issues are somehow combined. There is a general problem 
regarding finding installed fonts.

Thanks again!

A typeface definition normally has a matching monospace and math
