Was trying to keep this simple but I think I've complicated the regex now:

Basically, I want to remove all digits from a string - but taking into consideration that there may be a comma sign or a decimal.

Examples:

```
$13 -> 13
$13.95 -> 13
$1,300 -> 1300
$ 13 -> 13
Only 3 left -> 3
34 sold -> 34
34% -> 34
(45%) -> 45
($14) -> 14
£13 -> 13 (unicode u00A3)

```

Current regex in python:

```
re.match(ur"\$?\u00A3?(?:\s+)?((\d+)\,?(\d+)?)\%?(?:\.[0-9]*)?", value)

```
