[Gtk2hs-users] unicode strings and cairo

[Tim D. <tw...@do...>]

Hi,

A user of the charting library

http://hackage.haskell.org/package/Chart

has pointed out that it doesn't display unicode strings correctly. I 
suspect that this is because the library currently uses the cairo 
functions "selectFontFace" and "showText". In the documentation these 
are described:

"This function is meant to be used only for applications with simple 
font needs: Cairo doesn't provide for operations such as listing all 
available fonts on the system, and it is expected that most applications 
will need to use a more comprehensive font handling and text layout 
library in addition to cairo."

"NOTE: The showText 
<http://www.haskell.org/gtk2hs/docs/cairo-docs-0.11.0/Graphics-Rendering-Cairo.html#v%3AshowText> 
function call is part of what the cairo designers call the "toy" text 
API. It is convenient for short demos and simple programs, but it is not 
expected to be adequate for the most serious of text-using applications. "

Does this mean that I need to use the pango library for correctly 
displaying unicode? Can someone point me to a simple example using 
unicode+cairo?

Thanks,

Tim
