All major languages are supported in all features, including notes.
Except on reports where we know some languages do not display correctly during the session. (ie: Chinese).
The two largest groups of languages are UTF-8 and UTF-16: those that can be represented with 8 bytes of memory (UTF-8) and those that require more memory and 16 bytes: UTF-16.
Nearpod works based on UTF-8.
Most languages fit within 8 bytes.
Some major languages that do not are: some forms of Chinese, Japanese, some Thai dialects, Indian dialects, Arabic, and Russian.
