[Scilab-Dev] Test report of Chinese (or multibytes languages in general) locale mesages with Scilab 5-beta-1

[Sylvestre Ledru]

Hello Yung-Jang,

Many thanks for your work and investigation!
Seeing Scilab translated in Chinese is a nice reward after all the time
we spend (and will spend) on the localization.

I (and probably with Vincent, the console dev) will have a look to your
problem but the solution you propose won't be possible since we do not
use the glib.

Cheers,
Sylvestre
