Base64 将二进制转换为文本。如果您想将文本转换为 Base64 格式,则需要首先使用适当的编码(例如 UTF-8,UTF-16)将文本转换为二进制。
base64_encode
的utf8_encode
字符串进行base64_decode
后,只需对字符串进行utf8_decode
即可。仅供参考。 - LucasPython 2.5.1 (r251:54863, Jul 31 2008, 22:53:39)

byte[] encbuf;
encbuf = System.Text.Encoding.Unicode.GetBytes(input);
string encoded = Convert.ToBase64String(encbuf);
...并解码:
byte[] decbuff;
decbuff = Convert.FromBase64String(this.ToString());
string decoded = System.Text.Encoding.Unicode.GetString(decbuff);
您没有说明使用的是哪种语言,但可以尝试将字符串转换为字节数组(以您选择的语言方式完成),然后对该字节数组进行base64编码。
