Package: libghc-regex-pcre-dev
Version: 0.94.4-7
Severity: normal
When I try to run a program that searches for a (ASCII) string in a
UTF8-encoded string, I get a wierd "off-by-one" error:
I expect
title is |Page Title|
I get
title is |age Title'|
I can't find any docs that say I'm doing it wrong, or that I have to do
things a specific way to get unicode support.
(hopefully) A test-case haskell script is attached.
