[sword-devel] BibleMemorizer and Sword Text Encoding

Hi,

Create the SWMgr using a SWEncodingMgr object. Create that object using 
something like:
	new sword::EncodingFilterMgr( sword::ENC_UTF8 )

If you want to have keys in UTF8, use the StringMgr class. BibleTime includes 
the class BTStringMgr which is a ready to use implementation using Qt.
For example:
	StringMgr::setSystemStringMgr( new BTStringMgr() );

I usually use VerseKey::ParseVerseList with expandRange enabled. Do you set 
that ListKey to the module itself and iterate on the module or do you go 
through the list of refs using the ListKey functions?
I usually use the ListKey functions. 
But whatever you use, you can check in the iteration if more than a few 
chapters are displayed. If that's the case, stop the iteration.

I guess if you turn off AutoNormalization in VerseKey the parsing change the 
upper ref of a range to the next chapter. You can also check using Error() in 
VerseKey for parsing problems, afair.

I hope that all works :)
