Oh! =)

Hexdump gives:
2E 2F 4A 6F 73 C3 A9 20 47 6F 6E 7A C3 A1 6C 65 7A 20 2D 20 49 6E 20 4F 75 72 20 4E 61 74 75 72 65 2F 30 36 20 41 62 72 61 6D 2E 66 6C 61 63 0A

It looks to me as if spaces are the same (20) and that é are the only strange letters.

But shouldn't any wierd character be handled by ${line//[^a-z]/} since they would be NOT a-z, [^a-z] and should therefor be replaced with nothing?
