Description
Describe the problem
🐛 When Serial Monitor is used to display characters past the ASCII range printed by a non-native USB board, corruption occurs at various non-fixed positions in the output.
To reproduce
- Upload a sketch that prints characters past the ASCII range to serial:
×ばつØÙÚÛ"); delay(200); }">
void setup() { Serial.begin(115200); } void loop() { Serial.println("ASCII: !\"#$%&'()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_`abcdefghijklmnopqrstuvwxyz{|}~"); Serial.println("> ASCII: ¡¢£¤\¦§ ̈©a«¬® ̄°±23 ́μ¶· ×ばつØÙÚÛ"); delay(200); }
- Open Serial Monitor.
🐛 Some of the characters are replaced by�:

Additional context
I originally suspected the corruption might be caused by #375, but this bug persists even though that one has been resolved.
The delay duration has an influence on the position of the corruption and the manifestation is different from one board to another (less corruption on Leonardo and MKR, more on Nano Every).
The issue does not occur when using the Arduino IDE 1.8.19 Serial Monitor, even when the board is running the binary that produced the corrupted output in Arduino IDE 2.x (i.e., it's not related to the sketch having been compiled in Arduino IDE 2.x).
