(1.16) (Linux) the "--prefer-text" parameter does not work

To start scrcpy, on linux, I use the following command:
`scrcpy -S -b2M -m800 --prefer-text`
however, "`--prefer-text`" doesn't work, it's like I didn't add it there, so when I want to put an accent, it doesn't work ... for example:
instead of being "ã", he writes "~ a". I don't know if it is a bug or not in this version but this is the first time I use Scrcpy on Linux.

Start by reproducing the reported command, `scrcpy -S -b2M -m800 --prefer-text`, on Linux and compare accented input with and without `--prefer-text`. Trace the input handling reached by this option and confirm that characters such as `ã` are entered correctly when the fix is complete.
