Invalid UTF-8 string

[Stefan M. Brandl]

Hello,
just upgrade from rrdtool 1.3.8 to 1.3.9
and I get

(process:30282): Pango-WARNING **: Invalid UTF-8 string passed to pango_layout_set_text()

when I do a rrdtool graph ...
And have a ° (degree) sign in the GPRINT line.



Stefan

this is the kind of error you would get if you were running wit a
locale setting suggesting utf8 encoding and then inputing data
encoded with latin1 for example.

if you are using rrdtool from language bindings, make sure you call
setlocale and are not just setting the environment variable inside
you code.

cheers

Ups, you are right.
Setting the "correct" locale did the job.


Thanks
