Text rendering weird characters after move

I just recently moved our WordPress blog from one hosting company to another.

Here is an example of the weird characters that I see throughout the blog now after the move…

======== Begining of example…
Two primary xanthone extracts ”garcinol and mangostina” have “potential as anti-inflammatory agents with preliminary evidence for inhibiting cyclo-oxygenase (COX) enzymes and carcinogenic effects,” he said. A 2004 study explored the antiproliferative, apoptotic and antioxidative properties of crude methanolic extract (CME) from the pericarp of the mangosteen on human breast cancer cells.2 Researchers a€?found that antiproliferative effect of CME was associated with apoptosis on breast cancer cell line by determinations of morphological changes and oligonucleosomal DNA fragmentsa€?, and that the extract a€?has potential for cancer chemoprevention.a€?

Wayne Geilman, Ph.D., senior research scientist at Pure Fruit Technologies, added to the list of mangosteena€?s abilities: “We found the xanthones in mangosteen are COX-2 inhibitors,” he said. a€?If you stop that enzyme, you dona€?t get inflammation, and if you dona€?t get inflammation, you dona€?t get pain.” Other uses of mangosteen components include appetite suppression, and use in topical skin care products.

Does anyone know what the problem is and is there a central fix. I’d hate to have to go back and clean up all these entries individually (in some cases I know what the characters are suppose to be but in other cases I’d have to guess)

Thanks for any help in advance.
