BODEN £10 voucher query

[Bucharest]

Just received a £10 voucher code from Boden, only half way through the code is a funny "O" (with a diagonal line going through it) Where is that then on my computer?
Does Johnny think I'm Norwegian?

does that not just indicate it is a number rather than a letter O?

Does it?
Thank you! I'll give it a go!

hope it works!

The line means it's a zero and not the letter 'O'.
