Re: Regexp match with accented character problem

more:

having the string 'macskacicóca' it matches:

\\mmacskacic\\Wca'

so it matches:

\\mmacskacic\\W'

indicating that 'ó' is a non alphanumeric character, but strange enough 

but it doesn't:

\\mmacskacic\\W\\M

unless \M is with * quantifier.

Any idea or hint is highly appreciated.

Thanx in advance, 

Laslo

Perhaps helps:

'ó' matches 

\M

\M\M\M

\.*

but not \M\M\M\M or \M\M\M\W

These match:

E'\\mmacskacicó\M*'

E'\\mmacskacicó\s*'

E'\\mmacskacicó\W*'

with * quantifier. But not with + quantifier, or w/o any quantifier.

Also matches:

E'\\mmacskacicó\\Y'     (!!!)

E'\\mmacskacicó$'

The text is typed via psql using urxvt terminal.

Perhaps some unicode - wide charater kind of mess?

That might be a problem that 'ó' is not recognized as \w

Actually I do not know which class 'ó' is in. It matches:

test=# select * from texts where title ~* E'\\mmacskacic\\M';

    title     |           a_text           

--------------+----------------------------

 A macskacicó | A blah blah macskacicónak.

(1 row)

As if the end-of-word is at the last 'c' . ???

If the hex. code of 'ó' is 97 (dec.151) could someone hint me how to insert it into the expression?

Okay, I'm not sure what the problem is there then. :S  Hopefully
someone else can shed some light on it for you.
