Trying to edit a post earlier and everything after the input of the EURO currency-symbol was deleted - not once, but several times. It took me three attempts before I realised what was going on... 'Euro-Symbol' appeared as an 'A' with a squiggle in the edit, but no text after that appeared.
I've noticed on other threads I've attempted to edit that other currency symbols are often replaced with the Squiggle-A in the edit-text box, but previously, deleting it and retyping the correct symbol fixed it - not so with the 'Euro-Symbol'
