带有特殊字符的反向字符串

Question

我该怎么扭转这个字符串:???I？

我试过了:

"???I".split("").reverse()

但我得到了: ["I", "?", "?", "?"]

这意味着???被替换为三个字符.

预期产量应为: I???

Answer 1

使用https://github.com/orling/grapheme-splitter

\n\n

然后你可以做这样的事情：

\n\n

\r\n

\r\n

function GraphemeSplitter(){var e=0,r=1,n=2,t=3,i=4,u=5,f=6,o=7,a=8,h=9,c=10,l=11,s=12,d=13,v=14,g=15,x=16,p=17,O=0,y=1,m=2,A=3,C=4;function b(e,r){void 0===r&&(r=0);var
