Follow-up Comment #1:

Confirmed on a recent tip.

Currently Octave does not support UTF8 in regular expressions, although it is
not hard to add.  I've made an experimental patch that does so but it does
impact performance.  UTF8 is 23% slower than non-UTF8 pattern matching.  

Adding support for UTF8 is a big enough change that I am going to take the
issue to the Octave Maintainers mailing list so that we can make a decision
about how best to implement this.  It is also big enough that this will come
out not as a bug fix, but in the next major release of Octave (3.8.0).
