No such issue in Jira.
When I try to insert a link and perform a pagetitle search (in Russian), search results are shown in wrong encoding - see attached screenshot
TinyMCE 3.7.2.0 for MODx Revolution (installed through package management)
Browser Firefox 3.6.8
Revolution 2.0.0-pl
Database charset: utf8
PHP Version 5.2.12
MYSQL 5.0.90
FreeBSD 7.2-i386-20100301 i386
Apache
pdo_mysql PDO Driver for MySQL, client library version 5.0.90
Actally I think it’s MODx specific because of resource search - I had similar problem at 0.9.1 but in new infrastructure of Revolution I don’t know where to dig.
