I'll have to look further into it; routers2 should simply pull the text as defined in the config files and push it out to rrdtool -- which then passes it on to pango.
When moving to rrdtool 1.3.x, Tobi greatly changed the rendering to use pango/cairio (I think previously it simply wrote the text in the grpah using GD or similar). It maybe that this sort of character needs to be handled differently... However, you can do it from the command line, which is surprising to me. routers2 simply calls the function as if it were on a command line.
