博客涉及ASP和J#相关内容，ASP是微软开发的服务器端脚本环境，J#是微软为.NET平台设计的编程语言，二者在后端开发等信息技术领域有一定应用。

汉字转换为UTF-8

functionchinese2unicode(Str)
dimi
dimStr_one
dimStr_unicode
fori=1tolen(Str)
Str_one=Mid(Str,i,1)
Str_unicode=Str_unicode&chr(38)
Str_unicode=Str_unicode&chr(35)
Str_unicode=Str_unicode&chr(120)
Str_unicode=Str_unicode&Hex(ascw(Str_one))
Str_unicode=Str_unicode&chr(59)
next
Response.WriteStr_unicode
