[rrd-users] Putting a degree sign in an SVG?

[Anssi Saari]

I've been playing with generating SVGs with rrdgraph recently, but I
can't seem to be able to include a degree sign in an SVG graph. I'd like
to have vertical label like -v "Temperature (°C)". So far I've tried a
literal ISO-8859-1 and UTF-8 in the script, but that seems to generate
bad XML, or at least Firefox doesn't like it. That works for PNGs though.

<text font-size="14">Enc-Erature
(&#-1374389534;&#1080578375;&#17;&#1270128984;&#1270128984;P!&#1953724787;&#1952410981;&#7368037;</text>

It's also interesting that Temperature becomes Enc-Erature...

My other idea was using the XML notatation i.e. &#x00b0; but
unfortunately that's replaced with &amp;#x00b0; so I end up with the
literal string &#x00b0; in the graph instead of the degree sign...

So, any ideas? Using RRDtool 1.2.15 in Debian Etch.
