Question

VB6 unicode转汉字怎么转？

本人在接受HTTP的返回值时将之赋与一个变量TS，既 TS=Ahttprequest.ResponseTXT。
text1.text=TS后，看到结构如下：
{"status":1,"error":"","data":[{"id":"106530","pid":"106521","name":"\u767e0D05","top":"13"},
实际上name后面的"\u767e"换成中文是“百”。我尝试text2.text=StrConv("u767e",vbFromUnicode)后得到却是一个“?”.这是为什么？
如何才能得到正确的中文？

追问

兄台。我是用解码UNICODE UTF-8那一段吗。那个btemp数组参怎么给？
btemp2() as byte?
btemp2(0)="u"
.......
text2.text=Unicode8Decode(btemp2())?
