I have an IME that allows me to enter characters by their unicode code point.

For example, if I invoke the IME and then enter a9, the pre-edit in alacritty looks like this:

U+a9 = ©

When I press enter, this becomes

©

However, if I instead enter control characters, the output is unexpected:

After pressing enter, I get the expected output ^A and ^B for the first two and the effects of Ctrl-C and Ctrl-D for the latter two.
