Indeed, since all those terminal emulators basically emulate each-other
(or even share the underlying code).

You need to escape the backslashes since they're otherwise interpreted
as escape sequences for Emacs's string literals (and there's no such
thing as a \w escape sequence for Emacs string literals).
In any case a better solution is to change your .bashrc (or wherever
you set your PS1 prompt) so as to check the value of $TERM and use
different settings depending on the features suppported by the
corresponding terminal.
I personally only use `xterm', so I use code like:
if [[ $TERM == xterm* ]]; then
PROMPT=$(print -n "%{\033]0;%m%${my_uid}(#..-%n)\007%}%B%2c-%?%#%b ")
else
PS1="%B%${my_uid}(#..%n@)%m-%2c-%?%#%b "
fi
in my .zshrc, tho this is for Zsh so it won't work as is for you.
