# munin on unicode system

## [munin on unicode system](https://mo.homelinux.net/home/munin-unicode)

    12th Feb 2008   [monitoring](https://mo.homelinux.net/tag:monitoring#body-wrapper) [unicode](https://mo.homelinux.net/tag:unicode#body-wrapper)  

After installing a new Gentoo server running rrdtool-1.3.8 and munin-1.3.4 I received many mails from munin's cronjob, complaining the following
`(process:22748): Pango-WARNING **: Invalid UTF-8 string passed to pango_layout_set_text()`

A little research showed up something like the following [Bug#494547: munin cron job complains about pango invalid utf-8 string](http://groups.google.com/group/linux.debian.bugs.dist/browse_thread/thread/bf2df945046ada43).

The current version should work in any of the following two cases:

- the script's encoding matches the locale settings
- the script is encoded in UTF-8

A quick solution is makeing munin-graph to change munin's plugins texts to UTF-8.
A suitable patch can be found here: [380-munin-graph-utf8.patch](http://munin.projects.linpro.no/browser/branches/debian/lenny/trunk/debian/patches/380-munin-graph-utf8.patch.)

Apply the patch

```
patch -i /tmp/munin_1.3.4-r1_utf8.patch
```
