Uh, do you actually know what UTF-8 is?  \x00\xE4 would rather be
UTF-16BE.  The UTF-8 byte sequence is "\xc3\xa4" instead which works.
\x00 is not a valid number or character and you use it like a function
call because of failing to quote.  #\000 would be a character, but it
needs to be in octal, so we are talking here about
(list->string '(#\303 #\244))

$ is not a valid method to escape from Scheme into LilyPond but rather
the other way round.

#{ \markup \char ##x00e4 #} does not work since markup commands like
\char are only evaluated at markup interpretation time.

You can use (ly:char->utf8 #x00e4) instead.
