问题描述
我有一个这样的utf-8字符串:
=C3=A0=C3=A8=C3=AC=C3=B2=C3=B9
我需要将字符串解码为latin1。预期结果是:
àèìòù
这是我尝试失败的尝试:
utf8.decode(stringData.runes.toList())
解决方法
我解决了。
感谢@lenz注释和发现的here js函数,我使用以下函数解决了这个问题:
Audit.Core.Configuration.Setup()
.UseEntityFramework(_ => _
.AuditTypeMapper(t => typeof(AuditLog))
.AuditEntityAction<AuditLog>((ev,entry,entity) =>
{
var x = ev.CustomFields["User"];
...
})
.IgnoreMatchedProperties());
,并带有以下代码:
String decodeQuotedPrintable(String input) {
return input
// https://tools.ietf.org/html/rfc2045#section-6.7,rule 3:
// “Therefore,when decoding a `Quoted-Printable` body,any trailing white
// space on a line must be deleted,as it will necessarily have been added
// by intermediate transport agents.”
.replaceAll(RegExp(r'[\t\x20]$',multiLine: true),'')
// Remove hard line breaks preceded by `=`. Proper `Quoted-Printable`-
// encoded data only contains CRLF line endings,but for compatibility
// reasons we support separate CR and LF too.
.replaceAll(RegExp(r'=(?:\r\n?|\n|$)','')
// Decode escape sequences of the form `=XX` where `XX` is any
// combination of two hexidecimal digits. For optimal compatibility,// lowercase hexadecimal digits are supported as well. See
// https://tools.ietf.org/html/rfc2045#section-6.7,note 1.
.replaceAllMapped(RegExp(r'=([a-fA-F\d]{2})'),(match) {
var codePoint = int.parse(match[1],radix: 16);
return String.fromCharCode(codePoint);
});
}
