[Visualpython-users] unicode labels

[Flavio C. <fcc...@gm...>]

Hi,

apparently vpython 3.2.9 doesn't accept unicode strings in labels. It does,
however accept the latin-1(iso-8859-1) encoding without problems:

In [3]: a=3Dvisual.label(text=3D's=E3o')

In [4]: a.text=3Dunicode('s=E3o','latin-1')
---------------------------------------------------------------------------
Boost.Python.ArgumentError                             Traceback (most
recent call last)

/home/fccoelho/<console>

ArgumentError: Python argument types in
    None.None(label, unicode)
did not match C++ signature:
    None(visual::Label {lvalue}, std::string)

In [5]: unicode('s=E3o','latin-1')
Out[5]: u's\xe3o'

In [6]: print unicode('s=E3o','latin-1')
s=E3o

I need to put unicode strings into labels, is there any way of doing this?
Will the next release of vpython handle Unicode?

thanks,

The 4.x series should handle Unicode strings, but only on Linux+Gtk (or
one of the earlier Windows+GTK builds).
