It works on the version you have installed. I have success just
putting literal unicode into the pango layout. Where the 'X' in the
string below is actually and accented e that I am having trouble
making my browser accept but it is fine in emacs with utf coding
string (see attached for complete example)
# -*- coding: utf-8 -*-
gc = widget.window.new_gc()
context = widget.create_pango_context()
layout = widget.create_pango_layout(unicode('DXveloppXs et
fabriquXs', 'latin-1')
fontsize = 12 # points
scale = dpi/72.0
desc = pango.FontDescription('Bitstream Vera Sans, normal 12')
desc.set_size(int(scale*fontsize)*1024)
layout.set_font_description(desc)
inkRect, logicalRect = layout.get_pixel_extents()
l,b,w,h = inkRect
#l,b,w,h = logicalRect
x, y = 100, 100
widget.window.draw_rectangle( gc, 0, l+x, y+b, w, h)
widget.window.draw_layout(gc, x, y, layout=layout)
