How to draw ellipsis with drawUTF8 #2412

Closed JanB97 closed 3 months ago

JanB97 commented 3 months ago

I am using the u8g2_font_profont22_tf font. The font has the … (ellipsis) glyph, but I am unable to use it:

image

I tried adding "0xE2 0x80 0xA6" to the String and I have also tried just pasting the encoded "…", but it just doesn't get displayed.

What sequence do I need to include with this font?

Did you enable UTF8? What is the actual code?

JanB97 commented 3 months ago

Yes, this is my setup, I have one of those OLEDs that is 2 screens in one: image

The function I call is this: drawUTF8(22, 97, text.c_str());

That is declared like this: 

void drawUTF8(u8g2_uint_t x, u8g2_uint_t y, const char *s){
  u8g2_current->drawUTF8(x-offset,y,s);
}

In my String i tried using: "\u2026", (0xE2,0x80,0xA6) and "…". With "\u2026" and "…", it just is blank and with the byte codes it prints them as numbers.

These are the attempts: image

text is a String and cstr is a char array with 60 elements.

But "..." is at position "\x85"

You are right, its working with "\x85", thank you so much :) I searched everywhere but all I could find was the unicode. I think also finally understood the font overview.
