I don't think any of the macron word-based HTML entities work. You need to use &amp;#363; (&#363;) instead of &umacr;. It probably has something to do with some switch for Unicode being turned off.

Basically any HTML entity with a value over decimal 255 or hex 0xff won't render correctly as a word-based entity like #&amp;Amacr; (gives &Amacr;) which is the same as #&amp;256; (&#256;), whereas the word based entity &amp;yuml; (gives &yuml;) which is the same as #&amp;255; (&#255;). All the macron entities happen to be over 255.
