TextInput to display Korean characters

[Titus Cheng]

I have been working on this problem for a while and can't seem to find an answer to solve this particular problem.  I have a string that reads from a file which contains both English and Korean characters.  But the Korean text that comes out is a box with an 'x' inside.  I used unicode encoding and the Korean words are still not displaying problem. Any help would be appreciated.

[ZenCODE]

Try a posting a minimal example which we can help with.

def openFile(self, fname):

        file = codecs.open(fname, encoding='utf-8')

        file_str = file.read()

        file.close()

        return file_str 

def test(self, obj):

        MainApp.sourceInput.text = MainApp.fs.openFile(obj.text)

We can;t run that. Does it have a utf-8 header? Where/how is the font set? The example need to be complete and runnable.

if __name__ == '__main__':

    MainApp().run()

  Here is the complete code, I do have the utf-8 header.  What do you meant by font set?  It is necessary for the foreign language to be display properly?  Thanks for your help!

Yes, the font needs to be able to display Korean characters. You need to find a font that supportd these characters and then use that font in Kivy. That's almost certainly the issue here?

[Titus Cheng]

Thank ZenCODE!  Yes, I didn't realize it was needed until you mentioned it, I got used to other system where it automatically supports and didn't realize that this one didn't.  It is fixed now that I have added the fonts, thanks very much!

But I have another issue that once I type in Korean character, it doesn't automatically displays the individual letters right away, but rather it waits until I press space that the letters I typed is shown.  Do you happen to know this issue also?

[ZenCODE]

Glad you got it working :-)

As for the display issue, afraid not. Which version of kivy are you using? All I can suggest is experimenting and seeing whether it's a device/OS/setting specific issue.
