你如何回应一个4位数的统一code在Bash的性格吗? [英] How do you echo a 4-digit Unicode character in Bash?
问题描述
我想在UNI code骷髅添加到我的shell提示符(特别是'骷髅头'(U + 2620)),但我想不通的神奇咒语,使回波吐出,或任何其他4位统一code字符。两位数的人的很容易。例如,回声-e\\ X55。
I'd like to add the Unicode skull and crossbones to my shell prompt (specifically the 'SKULL AND CROSSBONES' (U+2620)), but I can't figure out the magic incantation to make echo spit it, or any other, 4-digit Unicode character. Two-digit one's are easy. For example, echo -e "\x55", .
在除它下面的答案应该指出的是,很明显,你的终端需要支持单向code的输出是你所期望的。 GNOME终端做了一个很好的工作,但它并不一定是默认打开。转到终端 - >设置字符编码,然后选择统一code(UTF-8)。
In addition to the answers below it should be noted that, obviously, your terminal needs to support Unicode for the output to be what you expect. gnome-terminal does a good job of this, but it isn't necessarily turned on by default. Go to Terminal-> Set Character Encoding and choose Unicode (UTF-8).
