There is an inconsistency in handling RE inline flags ( e.g. '(?iu)' ) when pattern consists of some unicode characters, for example characters in range from '\u1ea0' to '\u1ef9'. Please see code attached for a demonstration of the problem. |

I see this too. Maybe Fredrik understands? |

Looks like the wrong execution flags are being passed to the function
that creates the actual pattern object; the SRE compiler does the right
thing, but the engine isn't running with the right flags in the last
case. Changing the call to _sre.compile in sre_compile.py to:
return _sre.compile(
pattern, flags | p.pattern.flags, code,
p.pattern.groups-1,
groupindex, indexgroup
)
should do the trick, I think. (got no time to fix my broken Python SVN
setup right now, but if someone wants to verify this and add the
necessary tests to the test suite, be my guest).
