ssd1331 Multi-Language Font

[danjperron]

I start to use the ssd1331 oled display with my ESP32 and found out that the current font converter from Adafruit wasn't doing any multi-language font and it converts the font into C code .

Then i modified the fontconvert.c to enable utf-8 character and create a python module containing the font.

This way I was able to write sentence in French. The code is not complete but works enough to make it available.

I did compile the C code using a rasbperry Pi and I had to upgrade the freeType library . First by remove it and then install it using the source code https://www.freetype.org.
I also change my locales on Linux to get the correct language settings.


The way it works is by looking at one index to check if the utf-8 character is inside the font .


This is Adafruit Github with the original font converter.

And this is my fontconverter to create Python font modules with multi-language.

Just change/add into the contents of the variable List inside fontconvert.c and make

You might like to look at nano-gui which supports these displays. Fonts are created as Python source files uding font-to-py. This supports multi-lingual fonts and converts industry standard font files to Python source. The Python files are designed so that, if they are frozen as bytecode, their RAM usage is very small.
