ah yes you are right -- I've made the implicit assumption that his
file was already utf-8 encoded .
 I'm using only utf-8 from long time and I almost forget about
! String contains an invalid utf-8 sequence.

(I believe  he met the error during the next tries because he wrote

)
What I meant was, as I wrote below,
"To allow backward compatibility, the 128 ASCII and 256 ISO-8859-1
(Latin 1) characters are assigned Unicode/UCS code points that are the
same as their codes in the earlier standards"
and this is true only for iso-8859-1 .
