[ ToucgGFX ] Issue when display string in TextArea

[HPham.1590]

Hello, I'm trying to display a random String in TextArea.

But when I call this function, there is too much ???? was displayed.

Below is my code, anyone can tell me what's wrong?

Many thanks,

Hieu

	const char * test = "Hello World";
	Unicode::snprintf(RoomHeaderNameBuffer, ROOMHEADERNAME_SIZE, "%s", test);
	RoomHeaderName.invalidate();

And my TextArea Wildcard configuration

    RoomHeaderName.setXY(202, 13);
    RoomHeaderName.setColor(touchgfx::Color::getColorFrom24BitRGB(33, 49, 89));
    RoomHeaderName.setLinespacing(0);
    Unicode::snprintf(RoomHeaderNameBuffer, ROOMHEADERNAME_SIZE, "%s", touchgfx::TypedText(T_SINGLEUSEID130).getText());
    RoomHeaderName.setWildcard(RoomHeaderNameBuffer);
    RoomHeaderName.resizeToCurrentText();
    RoomHeaderName.setTypedText(touchgfx::TypedText(T_SINGLEUSEID129));

Hello,

It's because you didn't tell TouchGFX that the letters in Hello World had to be included when compiling and linking.

To make TouchGFX know about these letters, you can either create a Resource "Hello World" or add "a-zA-Z" to the WildCard Ranges field of your Typography.

Thank you, Alexandre.

I also found my issue yesterday. But now I have other question, Can I use Vietnamese in TouchGFX? I didn't found relate document about this language.

I believe it is supported as it is similar to the latin alphabet.
