Re: [Plplot-devel] Re: Unicode and plplot

[<hba...@ma...>]

Per has been struggling to get the AquaTerm driver to properly display
example 24, which it should handle now that it is unicode enabled. This
was difficult because it looks like PLplot doesn't always use UCS4 for
text. Was it incorrect to assume that all PLplot text that is sent to
a driver is UCS4? Is there some way to tell otherwise? Since the AquaTerm 
driver does its own unicode conversion (i.e. UCS4 -> UTF8) it gets 
very confused if the text is already UTF8.
