Write a slashed zero

Oh yes, I forgot about those foreigners who don't speak like us.
The slashed 0 to differentiate the 0 from the O is a remnant of old machines and systems, and in fonts where this difference isn't obvious (like in DOS)
it's a matter of font, not character; it is obtained by typing 0
on typewriters, it was achieved by overlaying the / onto 0, but this option is lost on computers.

Stop failing the Turing test!

me.....seriously, your advice isn't working :s......it's "slightly" annoying!! --"
don't you know how to do it differently? :\

You can use alt + 0248 for ø or alt + 0216 for Ø
And if that doesn't work, change your computer.
