I want to remove all strings beginning with "\u" until the first whitespace or punctuation

```
INPUT
Baby gift sets avalible from \u00a37.
to \u20ac 500 persons able to meet the conditions.
\u20ac 50 million.

OUTPUT
Baby gift sets avalible from.
to 500 persons able to meet the conditions.
50 million.

```

I tried:
 `sed 's/"\u"[a-z][0-9]//g' input`

However i can't seem to match *until* whitespace.. any help would be appreciated!
