For characters specified in octal

=F3 =3D octal code 227
=F2 =3D octal code 230
=FC =3D octal code 237

Use the Octal escape \num
a backslashed two or three digit octal number matches the character
with the specified value

For characters specified in hexadecimal

=F3 =3D hex code 97
=F2 =3D hex code 98
=FC =3D hex code 9f

Use the Hexadecimal escape \xnum
a backslashed x followed by one or two hexadecimal digits matches the chara=
cter
with that hexadecimal value.

For your Husker D=FC album you might consider:

the latin-1 (iso-8859-1) encoding popular on the web so...
to match any of the lowercase u's =3D [u\xf9-\xfc]
