Sorry, that was not actually elaborate. Now I think it
never worked at all.

In the meantime I received an answer in ruby-core and it
seems Matz just _planned_ to implement it but didn't have
the time yet.

The problem arises when my program is run on SuSE Linux
where the default encoding is UTF-8.

A better way to test in which encoding you reside is:

    "��" =~ /./
    puts $&.length

This gives 1 in `None' and 2 in `UTF-8'.

This has no influence on how the source code is read. The
string "�" produces an error when `ruby -Ku' is called.

Of course I should have written "\xc3\xa4" and "\xc3".

Sorry again for the noise.

Bertram
