u8g2_GetUTF8Width problem on cyrillic strings #693

Closed karawin closed 6 years ago

karawin commented 6 years ago

It seems that the function u8g2_GetUTF8Width has a problem on utf8 cyrillic (and may be other) strings.

The string "Супердискотека 90Ñ…" ie:"Супердискотека 90х" return 19

While the string "Virgin Radio New" return 80

olikraus commented 6 years ago

Which font did you use?

karawin commented 6 years ago

u8g2_font_6x13_t_cyrillic

olikraus commented 6 years ago

Ok, good. Can you post the complete code?

karawin commented 6 years ago

It is a big project https://github.com/karawin/Ka-Radio32 but the github is not up to date. output of scrollU8g2 function x= 128,scroll: +iline[i]= 0, len=43, x-onechar= 124 scroll: len=19, num= 20, str=Супердискотека 90х

The concerned module is addonu8g2.c `/**

hmmm... thats too much. Let me ask differently. Can you provide a small piece of complete code, which demonstrates the problem?

karawin commented 6 years ago

I don't have an arduino installed with u8g2 but it may be something like

include

include "u8g2.h"

int main() {

char str1[100]; char str2[100];

unsigned int len1,len2;

strcpy(str1,"Супердискотека 90х"); strcpy(str2,"Virgin Radio New");

u8g2_t u8g2; u8g2_Begin(&u8g2);

u8g2_SetFont(&u8g2, u8g2_font_6x13_t_cyrillic);

len1 = u8g2_GetUTF8Width(&u8g2,str1); len2 = u8g2_GetUTF8Width(&u8g2,str2);

printf("len1: %d, str1: %s\n",len1,str1); printf("len2: %d, str2: %s\n",len2,str2);

return 0;

}

It works as expected. The output is:

len1: 107, str1: Супердискотека 90х
len2: 95, str2: Virgin Radio New

Ok thanks. I think i made a beginner bug in the logic of the code. Thanks for your help and sorry.

olikraus commented 6 years ago

no problem

karawin commented 6 years ago

I made a set of fonts with latin and cyrillic all in one bult with bdfconv.exe -v -f 1 -m "$20-$ff,$a0-$ff,$a0-$17F,$0400-$045f" ...... at https://github.com/karawin/Ka-Radio32/blob/master/components/u8g2/csrc/u8g2_karadio32_fonts.c and integrated in https://github.com/karawin/Ka-Radio32/blob/master/components/u8g2/csrc/u8g2.h

Thanks for your work. Is ucglib utf8 planned ?

karawin commented 6 years ago

Hum bdfconv.exe -v -f 1 -m "$20-$7f,$a0-$17F,$0400-$045f" ......

olikraus commented 6 years ago

There is a utf8 add on lib for the adafruit gfx lib for TFT displays.

karawin commented 6 years ago

May be;-) but i wrote hal for your libs. Both in one code with only one configuration parameter to choose the type of lcd. Thanks JP
