Not necessarily. It will work as long as the sequence of 3 bytes f�� is the
representation of the string you are looking for in the file, in that file's
encoding. grep does not validate anything, nor should it IMHO. If you want
to guarantee the encoding, use a converter like ICU's uconv(1) or iconv(1).
