You know, I just checked your other site
http://www.mainwc.com/ and it is doing the same thing at Yahoo -- the garbage characters. It too has the Mac encoding.
Same error on the cache page also:
The titles are not there and have the url instead.
This is all too strange. Somehow, Yahoo is getting screwed up with the encoding. That is obvious now. They are converting the plain text Html into something unintelligible.
You may want to ask them what is up. The only place I can see to do that is in the
comment box here. Hopefully they will see and respond to it. They should be made aware that there is something snafu to correct the problem.
