imperfect handling of international characters

[Andrei Mircea]

        When computing the position of the notes, in pieces with lyrics,
the length of each syllable is accounted for. However, the tex coding
sequences used to obtained accented and other international characters
(cedilla, breve..) are also included in this computation, leading to
incorrect (too large) room left for printing those syllables. As a result,
the notes' as well as the hyphens' positions are not as good as they could
(and should) be.
