RSFS Font

RSFS Font

[Troy Henderson]

I'm trying to follow

http://wiki.contextgarden.net/rsfs

to get a script L in math mode (to denote Laplace Transform) but to no
avail.  I followed the code in the first section, but I get the
following compilation error.  Any help is appreciated.

Hi Troy,

The following works fine for me in mkii, but not in mkiv since, as you observe, the command 
\purefamily
seems to have disappeared from mkiv:

%%%%%%%%%%%

     \definebodyfont [6pt,5pt,4pt] [mm] [mc=rsfs5 sa 1]
\stoptypescript

Sure, as we have a complete different model now as in mkiv we take 
complete freedom to divert from the regular tex approach of families.

Anyhow, the following shoudl work out ok. You need the beta that i just 
uploaded as some extra checks were needed because these are non typical 
fonts. This is just a test. In order to have a nice solution we'd have 
to define a proper virtual setup (so in fact symbol then becomes a 
collection of alternatives; of course we can consider adding them the 
base lm set instead)

Hans,

I updated my ConTeXt (by rerunning first-setup.sh and remaking the
format files), but I get the following error when compiling your code.

On my machine the rsfs font is shown under mkiv, but there a few issues with spacing of some characters as you may see in the resulting PDF. Hans gave a mission to Aditya, Mojca (and very remotely to me, given my more than limited skills…) to track down some of th eissues with math in mkiv. Aditya is right now travelling, so without an easy access the internet, beside being busy with his thesis. I am sure he will return soon and we will have some insights frm him and Hans.
