Asp.net 不能显示北欧的æøå;生成ics文件时(æ;ø;å;)
我是新来的,但有一个生成脚本的ics文件,工作100%的iCal和Outlook,但我看不出我如何修复编码 当我的数据库中有一个北欧字母(nordicæåå)的文本时,我得到的字母是?。 有人能帮我设置使用iso-8859-1吗 或者我需要用html标记(æøå)替换字母的6个替换代码吗 我的代码是Asp.net 不能显示北欧的æøå;生成ics文件时(æ;ø;å;),asp.net,vb.net,ado.net,outlook,icalendar,Asp.net,Vb.net,Ado.net,Outlook,Icalendar,我是新来的,但有一个生成脚本的ics文件,工作100%的iCal和Outlook,但我看不出我如何修复编码 当我的数据库中有一个北欧字母(nordicæåå)的文本时,我得到的字母是?。 有人能帮我设置使用iso-8859-1吗 或者我需要用html标记(æøå)替换字母的6个替换代码吗 我的代码是 Imports System.Data.OleDb Imports System.Data Imports RF.Event2 Partial Class _new Inherits System

将有问题的字符映射到“?”来写入流
您可以通过一些修改来修复代码并使其抵抗此错误:
Context.Response.ContentEncoding = Encoding.GetEncoding("iso-8859-1")
Context.Response.Charset = Context.Response.ContentEncoding.WebName
Context.Response.AddHeader("content-disposition", "inline;filename=Sport.ics")
' Write the bytes of the iCalendar item output to the resonse stream
Context.Response.BinaryWrite(Context.Response.ContentEncoding.GetBytes(ical.Output))
也许你需要使用UTF-8编码。要解决此问题,可以使用Fiddler之类的工具查看从服务器接收的实际字节。例如,对于ISO-8859-1,字符串
æå
应编码为0xE6 0xF8 0xE5
,而Ê255;
应编码为0xAF 0xCA 0xFF
,这是完全不同的。
