O With Line Through It
Hyphen letter O: Does it mean z or letter?
If it's a backslash Z, it's always Z. This will make it easier to read.
But to clarify ... in some Scandinavian languages (Danish, Norwegian) they have extra heads (ÃÂ¸ or Â˜). Rows are similar to Id r and are considered a letter in the alphabet.
A dash in the letter O means z.
