推荐答案

该消息字符的限制取决于你所使用的字母的字符位大小。对于标准的GSM 7位字母，字符数限制为160。对于一个8位的字母，它是140，和一个16位的字母，这听起来像您的情况，它只是70个字符。如果你要发送消息的特殊统一code字符，如那些非拉丁字母，那么你坚持了16位的字母，它的70个字符的限制。如果你能以某种方式转换的消息基本7位字母，您将有160个字符的限制。

The message character limit depends on the character bit-size of the alphabet you're using. For the standard GSM 7-bit alphabet, the character limit is 160. For an 8-bit alphabet, it is 140, and for a 16-bit alphabet, which sounds like your situation, it is only 70 characters. If you must send messages with special Unicode characters, like those in non-Latin alphabets, then you're stuck with the 16-bit alphabet, and its 70-character limit. If you can somehow convert the messages to the basic 7-bit alphabet, you will have the 160-character limit.
