My web site is hosted by Pow Web.
This has been encoded for shift JIS since its beginning several years ago. The Japanese looks fine on my desktop browsers (Firefox, Safari and Chrome)
But Japanese viewers are complaining that the Japanese characters are garbled on their smart phone browsers. I don't have a smart phone, but I see the problem on my Android tablet -- BUT ONLY ON THE INDEX PAGE; the other pages display Japanese just fine on my tablet.
If I duplicate the index page and upload it as index2.html then the characters display correctly. What is going on?
