Problem Description
Export page to word in Confluence 4.2 and 4.2.1 shows the content incorrectly, it seems like the html that is generated did not rendered correctly.

Findings
The issue didn't affect MS Office 2007, but it affects Open Office. The tags generated has '3D' before the quotation mark, after equal sign. For example it is generated like.

http-equiv=3D"Content-Type" 

Instead of

http-equiv="Content-Type"
