did you triy u"<font face='DejaVu'>abc<br/>€</font>"?

image_map is something introduced by Massimo :-)

I'ld have to debug the html generation, it should respect the <font
face=""> but ...
If you can, please send me the .py so it easier to debug.

I've noticed this too.
The pkl file is a temporary file (in python pickle format) just to
speed up ttf handling, it should be generated on each install.
Anyway it is not a major issue, it could be removed and it will be
generated automatically with the new path (I think this should be done
in case of error, instead of throwing an exception about the absolute
path).
If you can please fill an issue in the fpdf project site so it is not lost.
The change should be trivial to support relative paths, but I'm afraid
I could have no time right now.
