Hello,
ISSUE:
I can’t report a bug on the tracker as the login page displays:
"Internal error
An error occurred on the page you were trying to access.
If you continue to experience problems please contact your Redmine
administrator for assistance.
If you are the Redmine administrator, check your log files for details
about the error.

BUG:
2.6.3 :049 > 'SHOP' =~ /[xo]/i
=> 2
2.6.3 :050 > 'CAFÉ' =~ /[é]/i
=> 3
2.6.3 :051 > 'CAFÉ' =~ /[xé]/i
=> nil
2.6.3 :052 > 'CAFÉ' =~ /[xÉ]/i
=> 3
Expected result:
2.6.3 :051 > 'CAFÉ' =~ /[xé]/i
=> 3
I tested it on random regex online pages.
It does not match on https://regex101.com/
It matches on:
https://www.regextester.com/
https://www.freeformatter.com/regex-tester.html
(Ignore case turned on).
The reason I suppose it’s more like a bug than a feature is the fact that
/[é]/i matches 'CAFÉ'. If the //i didn’t work for UTF-8 characters then the
/[é]/i wouldn’t match it either. For example, [é] does not match 'CAFÉ' on
I could not find a page or a system that behaves the same way as Ruby does.
For example, it matches in PostgreSQL 10 (under FreeBSD 12) too:
# select 'CAFÉ'~ '[xé]';
?column?
···
----------
f
(1 row)
# select 'CAFÉ' ~* '[xé]';
?column?
----------
t
(1 row)
Tested it in IRB on macOS and FreeBSD.
