PERL cgi script... extra character driving me crazy
I'm using a PERL cgi script that uses rrdtool to make graphs. I can't get the syntax correct to use a degree sign (alt+0176 like this °) and also using a variable.

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:
Code:
"GPRINT:rech_c:LAST: %5.2lf °F set in $rhty \\n",

The character is UTF-8, you want to convert it to whatever character set the rest of the characters are in.

Thanks for the tip. I found out I'm using the ISO-8859-1 character set. If I place my °F into a variable, what is the syntax to convert it to ISO-8859-1?
