<em> and <i> sometimes displays italic gibberish
 

From time to time I've seen a line of gibberish like this:
[INDENT]Ygnn.vqtc(.yg)xg"iqv"c" (and so on)[/INDENT]
I just looked into the problem on this page (which will disappear after July 2):
[INDENT][url]http://maczot.com/wow/[/url][/INDENT]
The gibberish text is displayed in italics and comes from <em> tags. The first gibberish is the second sentence of the first paragraph (after "... multiple clipboard & scrapbook.").

Using View Source, I changed the <em> tags to <i> with the same result.

When I selected the gibberish and dragged the selected text into this message, the correct text appeared.

The italic text is fine in Savari 2.0.3 and WebKit r13302.

A variation of the problem text appears near the top of another page, with the italic text correctly displayed:
[INDENT][url]http://www.maczot.com/discuss/[/url][/INDENT]
Do others see the same gibberish?

It looks fine to me.

I've seen this with Safari though. It's a font conflict.

How do I find the font problem?

The italic gibberish is showing up more often than before (or perhaps the font gods are angry I reported the problem).

Since others are not seeing the problem, how do I go about resolving it on my Mac?

Font cache corruption
 

I finally got annoyed enough by this problem (which also showed up occasionally in Mail) that I tracked down and zapped it.

VersionTracker led me to Mark Douma's [URL="http://homepage.mac.com/mdouma46/fontfinagler/"]Font Finagler[/URL], which cleaned my Tiger font caches and restored proper italic text.
