There have been several occasions where I see referring search terms in analytics and in logs. I copy the text and get odd results, mainly because the text isn't what it appears to be.
Example Search Term <-- in Latin text just as I have typed.
Then: Example Search Term <-- Text looks like stuff printed on some products imported from China. At least with Arial, but type looks thinner.
Then: Example Search Term <-- Looks exactly like Latin text, but search results are almost exclusively from Russian sites.
The problem is that with Google, I never seem to be able to find any of the sites I monitor in the actual results while Bing actually seems to display the sites.
I am well aware that it is possible to use a Cyrillic charset and make it look like Latin, but what is the Chinese charset called? What is the text actually referred to as? It doesn't pass a DIFF test.
Add: I would paste examples here, but the only examples I have would be too specific.
