Cyrillic Font Rendering Issues on 64x32 LED Matrix Display #664

Open Ezopython opened 3 months ago

Ezopython commented 3 months ago

Describe the bug I am experiencing issues with rendering Cyrillic characters on a 64x32 LED matrix display. The text appears distorted, with characters overlapping and misaligned.

To Reproduce Steps to reproduce the behavior:

Use the provided Cyrillic font data with the Adafruit GFX or similar library. Render text on a 64x32 LED matrix display. Observe the overlapping and misaligned characters. Expected behavior The Cyrillic characters should render clearly without overlapping, with correct alignment and spacing.

Your Cyrillic font bitmaps and glyphs are empty, what are you expecting to see?

{ 0, 8, 11, 9, 0, -11 }, // 0x0410 'А'

According to the comments, you use UTF16 cyrillic codes, while Arduino IDE uses UTF8 codes. For example, the 'А' letter has code 0xD090 in UTF8 codetable.

See more: https://www.fileformat.info/info/unicode/char/0410/index.htm

PS And as I think, this issue has nothing to do with the library.

Ezopython commented 3 months ago

thans for avialable for me, i use vscode-> PlatformIO IDE which is same with arduino IDE i guess. Here is my full bitmap and glyph data for all Cyrillic characters in UTF-8 encoding according to advise. after try below code i got nothing displayed

include

it might be a problem with a panel itself - did you test it with standard latin font and text?

yes its fine for latin font Image_20240812210701

board707 commented 3 months ago

It seems that the print() method does not support working with multi-byte characters. In such a situation, I can advise using a font in a single-byte encoding of the cyrillic character set - for example Win-1251 or Koi8. And the text from the arduino should first be recoded from UTF8 to font encoding. You can see an example in my DMD-STM32 library

DMD-STM32

can i use this library directly with my ESP32

board707 commented 3 months ago

No, but you could to use this code as an example and port it to your sketch

Ezopython commented 2 months ago

does this library support Cyrillic Font in future with ESP32

board707 commented 2 months ago

What is the library you mean?
