invalid character

基本解释

A better error message reads, "The zip code field contains an invalid character.
而更好的错误消息应该是这样：“邮政编码字段中包含一个无效字符。
Thus, the space, the invalid character, needs to be converted into an escaped hexadecimal encoding and can be decoded later.
这样，需要将该空格（一个无效的字符）转换为转义的十六进制编码，并可在以后对该编码进行解码。
The invalid character might be in the argument of this method or in an argument of previous methods that were writing to the buffer.
无效的字元可能是在这个方法的引数中，或在先前已写入至缓冲区的方法的引数中。
