Can anybody please tell me what is the range of Unicode printable characters? [e.g. Ascii printable character range is \u0020 - \u007f]
推荐答案
请参阅
您可能想特别查看C0和C1控制字符
You might want to look especially at C0 and C1 control character http://en.wikipedia.org/wiki/C0_and_C1_control_codes
维基说，C0控制字符在U + 0000-U + 001F和U + 007F（与ASCII相同）和C1控制字符在C控制字符之外的U + 0080-U + 009F
The wiki says, the C0 control character is in the range U+0000—U+001F and U+007F (which is the same range as ASCII) and C1 control character is in the range U+0080—U+009F
的范围内，Unicode也有数百个格式化控制字符零宽度非联接器，这使得字符间距更接近，或双向文本控制。这种格式化控制字符是分散的。
other than C-control character, Unicode also has hundreds of formatting control characters, e.g. zero-width non-joiner, which makes character spacing closer, or bidirectional text control. This formatting control characters are rather scattered.
更重要的是，你在做什么，需要你知道Unicode的不可打印字符？很可能，无论你想做什么是错误的方法来解决你的问题。
More importantly, what are you doing that requires you to know Unicode's non-printable characters? More likely than not, whatever you're trying to do is the wrong approach to solve your problem.
