This enables non english users (all iso8859-*
encodings) to use their own characters beyond ascii in
With the information from new listbox where encoding
can be specified it
translates characters from textbox into unicode before
sending them to freetype to render.
The characters in textbox are still shown in
cinelerra's default iso8859-1 font, but they are
rendered properly in compositor...
There should be a way to set cinelerra's default font's
encoding in order to fix this, but i think this kind of
patch would be to invasive at the moment...
Also it simplifies font loading by using freetype
internal rutines (I don't know why the complicated way
was chosen in the first place).
