Copy the following and paste it at the REPL:

z = 'ÇØĚ'

In paste mode it works, but not at the REPL prompt where the string contents disappears.

MicroPython v1.9.1-399-g40ae6724 running on an ESP32
when i cut 10/5 - 20/10 from my editor and paste it into repl all is good.
but when i cut (x/5) – (y/10) and paste it into repl the minus sign has dissapeared.
all works well under python3 in terminal mode.

MicroPython v1.9.1-399-g40ae6724 on 2017-08-15; ESP32 module with ESP32

x,y = 10,20
10/5 - 20/10
0.0
(x/5) (y/10)
Traceback (most recent call last):

Both issues describe characters being silently dropped during paste into the REPL. The query (#2789) is explicitly about multi-byte UTF-8 characters (e.g. 'ÇØĚ'). The candidate (#3278) describes a "minus sign" disappearing, but the "–" in the pasted expression is almost certainly an en dash (U+2013), a multi-byte UTF-8 character — the user likely didn't notice it was Unicode rather than ASCII '-'. This means both likely stem from the same root cause: the REPL dropping non-ASCII bytes during interactive paste. However, the candidate is ESP32-specific and the symptom is reported as a single character loss rather than the general Unicode support framing of the query. Without a confirmed shared fix, this is RELATED rather than LIKELY_DUPLICATE.

Suggested action

Link the two issues as likely sharing the same root cause (UTF-8 byte dropping in REPL input path). If #2789 gets a fix, verify it also resolves the en-dash case in #3278. Do not close either without confirmation.
