The capital A with a hat is caused when our server mis-interprets what your browser sends. From Wikipedia....

For example, the pound sign "£" will appear as "£" if it was encoded by the sender as UTF-8 but interpreted by the recipient as CP1252 or ISO 8859-1. If iterated, this can lead to "£", "£", etc.

Hi everyone,

Sorry about that! Don't know where the A came from, but we'll see if Tech do.

My previous post looks OK on the desktop site but shows a variety of &pound combinations on the iPhone app. Thanks for raising this, I'll add it to the list.

£testing £1 £ 2 3£

Evenin all, £ works fine on the ole laptop. Will ask tech bods to check it out on the app.
