[rrd-users] strange character with a degree sign in a GPRINT line

I'm using a PERL cgi script that uses rrdtool 1.3.2 to make graphs. I can't
get the syntax correct to use a degree sign (alt+0176 like this °) and
also call a variable in my GPRINT line.
If I use single quotes, I can't call the variable. If I use double
quotes, there is an extra symbol (Â) before the ° which goes away if I
use double quotes without the variable.
A picture is worth 1000 words (I circled the error in pink):
Here is the relevant line of code that produces that extra letter:
"GPRINT:rech_c:LAST: %5.2lf °F set in $rhty \\n",
Is this a bug or is it me not knowing enough PERL/rrdtool?
