bash mi dice:
-bash: $'\303\240': command not found
sapete mica in che codice sono quei numeri? perche' da me A accento
grave e' il decimale 224 battuto nel tastierino numerico con <ALT>.
L'ottale corrispondente a (224)_10 e' (340)_8 mentre l'esadecimale e'
invece 0xe0, quindi nessuno dei due ha a che vedere con 303 240.

Dal man bash:

Words of the form $'string' are treated specially. The word expands to
string, with backslash-escaped characters replaced as specified by the
ANSI C standard. Backslash escape sequences, if present, are decoded as
follows:
[...]
\nnn the eight-bit character whose value is the octal
value nnn (one to three digits)
\xHH the eight-bit character whose value is the
hexadecimal value HH (one or two
hex digits)
\uHHHH the Unicode (ISO/IEC 10646) character whose value
is the hexadecimal value
HHHH (one to four hex digits)
\UHHHHHHHH
the Unicode (ISO/IEC 10646) character whose value is
the hexadecimal value
HHHHHHHH (one to eight hex digits)
\cx a control-x character

The expanded result is single-quoted, as if the dollar sign had
not been present.

A double-quoted string preceded by a dollar sign ($"string") will
cause the string to be translated according to the current locale. If
the current locale is C or POSIX, the dollar sign is ignored. If the
string is translated and replaced, the replacement is double-quoted.

OK e grazie, scioccamente non ho pensato di guardare man bash.
