128个US-ASCII字符只需一个字节编码(Unicode范围由U+0000至U+007F)。 带有附加符号的拉丁文、希腊文、西里尔字母、亚美尼亚语、希伯来文、阿拉伯文、叙利亚文及它拿字母则需要二个字节编码(Unicode范围由U+0080至U+07FF)。 其他基本多文种平面(BMP)中的字符(这包含了大部分常用字)使用三个字节编码。 其他极少使...
ASCII字符集:主要包括控制字符(回车键、退格、换行键等);可显示字符(英文大小写字符、阿拉伯数字和西文符号)。 ASCII编码:将ASCII字符集转换为计算机可以接受的数字系统的数的规则。使用7位(bits)表示一个字符,共128字符;但是7位编码的字符集只能支持128个字符,为了表示更多的欧洲常用字符对ASCII进行了扩展,ASCII扩展...

Unfortunately, GSM-7 is not a supported character encoding in many text editors. Even setting encoding to ASCII (or US_ASCII, or UTF-8) will not guarantee that text you write will be limited to GSM-7. You can use the above linked tool to quickly check the number of segments - that ...
