我从大型机应用程序获取数据。该文件是'sample.txt'文件的名称。当我通过'FTP'使用java代码读取数据以将其数据存储到oracle数据库时。它在名称字段中显示一些特殊字符。另外一个信息我们的产品，我们也使用国际化。我们使用葡萄牙语，西班牙语，英语。我使用独立的java程序运行这个。这真的是使用java的FTP代码的原因吗？
例如给定的输入，
DTALRVAQCRAÜL TORRENTS +34 93 8640317 +34 93 8640304 [email protected] 20100511FAO
DTALRVAQCRAÜL TORRENTS +34 93 8640317 +34 93 8640304 [email protected] 20100511FAO
输出，
DTALRVAQCRAðL TORRENTS +34 93 8640317 +34 93 8640304 [email protected] 20100511FAO
DTALRVAQCRAðL TORRENTS +34 93 8640317 +34 93 8640304 [email protected] 20100511FAO

我该如何恢复问题。 –
**补充：**此外，如果文本文件实际上在CP1252中，则它将不能包含来自不同语言的字符。在这种情况下，最好切换到UTF-8。 – bezmax
@KallarMannargudi找出您的文本文件的实际编码。当你这样做时 - 在该行代码中指定它。 – bezmax
