直接读取的方法与UTF-8编码简体汉字串读写文件的读文件操作相同。

2).将字串直接写入文件后再读取转换：

直接写文件的方法与UTF-8编码简体汉字串读写文件的写文件操作相同。

//读取后转换 RFs FileServerSession; RFile file; User::LeaveIfError(FileServerSession.Connect()); CleanupClosePushL(FileServerSession); User::LeaveIfError(file.Open(FileServerSession,KHelloFileName, EFileStreamText)); CleanupClosePushL(file); RFileReadStream StreamReadFromFile(file); CleanupClosePushL(StreamReadFromFile); HBufC* StreamData = HBufC::NewLC(StreamReadFromFile, 32); HBufC8* StreamData8 =
