Looks like there are not enough tests for the numbers that start with region code.
Namely, '0034 567890' and '34 567890' should not yield a match.
Most of the published solutions fail on these examples.
hkmt and friends are the only ones who nailed it. All glory to them!

' 034 567890' (with a leading space) probably should yield a match (there were tests with a leading space before the country code that were supposed to yeald a match).
This one fails for all published solutions. Including mine :)

Also, some of the published solutions fail on '0012 34 567890'.
How on earth could they be submitted in the first place?
