It seems that your patch is different from mine:
Your:
- if ( m_wiki.contains( "charset=utf-8" ) ) {
+ if ( m_wiki.contains( "charset=utf-8", FALSE ) ) {
Mine:
- if ( m_wiki.contains( "charset=utf-8" ) ) {
+ if ( m_wiki.contains( "charset=UTF-8" ) ) {
The encoding string should be in capital letters...
