Thanks for the quick reply!

From your link, I downloaded reg.zip and merged DisableSearchNonAsciiTextNonCaseSensitive.reg and restarted UR. Then I tried:

1. Exported the same item and the Item Text remained lowercase.
2. Refreshed the item, exported it, and the Item Text remained lowercase.
3. Cut the RTF text, saved, and pasted the RTF text, saved, exported it, and the case is now preserved.

So the SearchNonAsciiTextNonCaseSensitive registry flag did the trick.
But is there a way to globally update Item Text from Item Details (RTF), to apply the registry flag change?
