Calc still doesn't understand the euro symbol as a currency.
Try pasting in the following:
€85.00
€56.00
€52.00
€44.00
If you change the cell format to 'currency', it silently quotes the entries making them literal values (the leading tick mark is only visible in the formula box): '€85.00
'€56.00
'€52.00
'€44.00
Now it's impossible to treat them as numeric values without doing a weird regex find/replace [1]. This doesn't happen with sterling or pound.
