Langs: can more languages be supported?

[fangfangbest]

i have got equ, eng and osd in the language list and if it is possible to support other languages like Chinese

[jflesch]

The list of languages available depends on what's installed on your system.

For example, on Ubuntu/Debian/etc, if you use Tesseract, you can install the Chinese data files with the following command:
sudo apt install tesseract-ocr-chi-sim tesseract-ocr-chi-tra
(chi-sim = simplified Chinese ; chi-tra = traditional Chinese).

For a complete list of supported languages:
apt search tesseract-ocr- / Tesseract wiki
