This is AFAICS an instance of bug PR#14408 : it seems that in UTF-8
locales the grammar generated by the TRE engine for repetitions is in
odd cases buggy. And as the author has vanished, our hopes of his
fixing it are slim.
Try perl=TRUE .

Dear R users,
the way I understand the documentation of sub() and regexp the following code:
sub('[[:digit:]]{1,2}', '', '9ewww')
... should yield:
'ewww'
It returns, however:
'www'
Why is this the case? My code should just substitute 1 (minimum) or up to 2
(maximum) digits, i.e. numbers and not the 'e' in the string. Do I misinterpret
something here?
Thanks for any ideas
Jannis
