iOS如何解码ISO6937编码的文本？

Question

我正在实施电视解析器软件。

在捷克语时，我发现EPG由 ISO6937 编码。

我使用以下API进行解码并切换到NSString。

- (instancetype)initWithBytes:(const void *)bytes length:(NSUInteger)len encoding:(NSStringEncoding)encoding;

但我找不到编码ENUM。 CFStringConvertEncodingToNSStringEncoding(kCFStringEncodingISOLatin2)不正确。

有人可以帮助我吗？

如果您提到的编码不起作用，请尝试以下编码

CFStringConvertEncodingToNSStringEncoding(kCFStringEncodingMacCentralEurRoman)

或

NSISOLatin2StringEncoding
