Wireshark · Wireshark-dev: [Wireshark-dev] non-ASCII characters

[Andreas <AndreasSander1@xxxxxxx>]

I write a dissector for a protocol that transport measurement values for 
pressure and temperature and so on. I would like to display the values 
with proto_tree_add_float() with the correct unit. But the °C symbol as 
well as µA is not displayed correctly.

Is there a way display this character set specific characters in 
Wireshark? How should I encode these characters that the GTK UI displays 
the nice "°C" so that I can avoid "degrees centigrade"?

I don't need to care for portability since I only write a dissector DLL 
for the Windows operating system.

Helge
