We're using the GetLegendGraphic WMS request on several instances of Geoserver 1.7.6. We can't determine which font is used to render the text in the legend.
We don't need lots of control over the font, but in one particular instance an inappropriate font is being selected (no Roman characters) and we'd like to change that.
We do have several non-Roman fonts involved here, and we've had no problems selecting appropriate fonts in the SLD. It's just the font used to render the legend that is perplexing us at the moment.

As far as I remember these improvements were actually implemented,
you can try to give them a go
Andrea,
Thank you. I certainly did go down that road.
Best I can tell, version 1.7.6 ignores LEGEND_OPTIONS in
GetLegendGraphic requests. (I tried it.) The option is documented in
the 2.0 manual, but it's not clear even there whether fontName was ever
implemented.
In any case, I don't have immediate control over the version running. I
was hoping someone might have an idea how to control the legend font in
1.7.x.

sigma.opengeo.org:8080/geoserver is a 1.7.6 instance.
The default output there is sans serif:
http://sigma.openplans.org:8080/geoserver/wms?REQUEST=GetLegendGraphic&VERSION=1.0.0&FORMAT=image/png&WIDTH=20&HEIGHT=20&LAYER=topp:states
If I change that to "Serif":
http://sigma.openplans.org:8080/geoserver/wms?REQUEST=GetLegendGraphic&VERSION=1.0.0&FORMAT=image/png&WIDTH=20&HEIGHT=20&LAYER=topp:states&legend_options=fontName:Serif
the font actually changes. It may be you're trying with a font name that
is not available to your runtime or that you're using the wrong case.
For example, "arial" won't work on Sigma since that is a unix machine
without the Microsoft web fonts installed, and it won't work on a
Windows machine either since the font name has case issues, but if you
use "Arial" is should work.
Cheers
Andrea

Dear Ron,
a question, are you trying to use this option for raster data or for
vector data, or both?
Simone.

If I change that to "Serif":
http://sigma.openplans.org:8080/geoserver/wms?REQUEST=GetLegendGraphic&VERSION=1.0.0&FORMAT=image/png&WIDTH=20&HEIGHT=20&LAYER=topp:states&legend_options=fontName:Serif

is not available to your runtime or that you're using the wrong case.
Andrea, thank you for the example. That solved it. I forced a rational font and it works.
On one server I'm working with, the default Java font has only one face. It was unresponsive to things like LEGEND_OPTIONS=fontStyle:bold, and it gave the impression it was ignoring that extension.
On another, SansSerif defaults to a font without a Roman character set. Those are both JVM problems I'll deal with separately.
Simone, this was for vector layers.
For what it's worth, then, I can take fontName to be included with all the other options at the bottom of this page:
http://docs.geoserver.org/2.0.x/en/user/services/wms/get_legend_graphic/legendgraphic.html
Once again, thank you very much for the help.
