nanogui: Thread: NanoX+FLTK+UTF-8

Hi all!

 

We had nano-x working with FLTK application finely on our target device.
Recently I have installed a UTF-8 patch from here
(http://www.oksidizer.com/software/fltk.html ) on FLTK 1.1.6 that we use
here. We had no problem with it on Linux X-Window and on Win32, - it did its
job and UTF-8 texts were displayed, however we've run into problems on the
target device on nano-x. All texts simply are not drawn by the applications.
i.e. all calls to text-drawing functions result in drawing nothing. 

 

It seems that our nano-x configuration is lacking something. Could anyone
suggest a solution to this?

 

Best Regards,

Ivan S. Tarapov

Sounds like the underlying text drawing functions when nano-X is
linked with X11 or win32 take the bytecodes passed and draw
the encoded strings properly, but when the drawing is using our
own framebuffer driver, this isn't happening.

I assume you're running NXLIB, and you'll have to change the
GrText functions in NXLIB to indicate that you're passing
UTF-8 formatted text to them.  See the docs on GrText
for more details.
