isprint should return true for umlaut characters on an ISO-8859-1
console, provided the locale ($LANG, $LC_CTYPE) matches the console.

The question is whether you want QEMU's debugging output to depend on
the current locale, or be the same for everyone.  If the former,
isprint is quite appropriate.  If the latter, restricting to ASCII is
appropriate.
