That’s the highlightjs library so any bug would be upstream.
Also looks like this works in cpp mode?
const char* NXT_CMD_END = "\xff\xff\xff";
Serial.print("page2.t0.txt=\"Any text\"");
Serial.print(NXT_CMD_END);
You can set a explicit language using the “info string” feature in a code block:
```cpp
your code here
```
will create a cpp flavored code block.
