It's not supposed to.  If you want that, just do an "echo" after the
read.

Confirmed on Debian 9 with locale en_US.UTF-8.  In an interactive shell,
issuing "read -n1 -e" and then typing í (Compose + ' + i) causes í to be
displayed, followed by a newline; the read command does not terminate.
Sending another character (e.g. space) causes that character to be
displayed, without a newline, but the read still does not terminate.
Pressing Enter finally terminates the read command, and issues TWO
shell prompts.

Repeating again, with "ájkEnter" as input, gives á + newline, jk + newline,
a shell prompt with "k" shown as an entered command, the error message
"bash: k: command not found", and then a second shell prompt.
The REPLY variable contains:

wooledg:~$ printf %s "$REPLY" | od -t x1
0000000 c3 6a
0000002

In other words, it contains the first byte of á (c3) and then the single
byte for j (6a), which I believ is not a valid character string.
