Hi, Multibyte encoding of my sample site was fixed to SJIS and it was effective for japanese only. Now, I change default encoding to UTF-8 and it can be change dynamically. Thank you.

tkanks a lot,it save me a lot of time because of your help.it suprise me that you are a japanese developer.what's the technical atmosphere of the Frontend in Japan 。

kazuhikoarase commented 7 years ago

Mostly projects are migration from the legacy system and taking a lot of cost for character conversion, encoding and Wareki (i.e. Heisei, Showa, ...) conversion. There are not technical and nothing interesting. So I must try a modern programming on github :)
