reverse string with special characters

Question

How can I reverse this string: हैंI ?

I tried:

"हैंI".split("").reverse()

But I got: ["I", "ं", "ै", "ह"]

It means that हैं was replaced to three characters.

The expected output should be: Iहैं

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

Then you can do something like this:

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 n=e.charCodeAt(r);if(55296<=n&&n<=56319&&r<e.length-1){var t=n;return 56320<=(i=e.charCodeAt(r+1))&&i<=57343?1024*(t-55296)+(i-56320)+65536:t}if(56320<=n&&n<=57343&&r>=1){var i=n;return 55296<=(t=e.charCodeAt(r-1))&&t<=56319?1024*(t-55296)+(i-56320)+65536:i}return n}function k(l,b,k){var B=[l].concat(b).concat([k]),G=B[B.length-2],S=k,I=B.lastIndexOf(v);if(I>1&&B.slice(1,I).every(function(e){return e==t})&&-1==[t,d,p].indexOf(l))return m;var j=B.lastIndexOf(i);if(j>0&&B.slice(1,j).every(function(e){return e==i})&&-1==[s,i].indexOf(G))return B.filter(function(e){return e==i}).length%2==1?A:C;if(G==e&&S==r)return O;if(G==n||G==e||G==r)return S==v&&b.every(function(e){return e==t})?m:y;if(S==n||S==e||S==r)return y;if(G==f&&(S==f||S==o||S==h||S==c))return O;if(!(G!=h&&G!=o||S!=o&&S!=a))return O;if((G==c||G==a)&&S==a)return O;if(S==t||S==g)return O;if(S==u)return O;if(G==s)return O;var q=-1!=B.indexOf(t)?B.lastIndexOf(t)-1:B.length-2;return-1!=[d,p].indexOf(B[q])&&B.slice(q+1,-1).every(function(e){return e==t})&&S==v?O:G==g&&-1!=[x,p].indexOf(S)?O:-1!=b.indexOf(i)?m:G==i&&S==i?O:y}function B(O){return

Answer 2

The main problem was finding a way of capturing "हैं" as a single character and not 3 seperate ones.

encodeURIComponent actually converts "हैंI" as "%E0%A4%B9%E0%A5%88%E0%A4%82I" which is much easier to handle with a regular expression.

Using String#match, Array#join, encodeURIComponent and decodeURIComponent

const res = decodeURIComponent(encodeURIComponent("हैंI")
.match(/(\%[A-F0-9]{2})+|./g)
.reverse().join(''))

console.log(res);

However, this fails if at least two of those special characters are side by side. As "%E0%A4%B9%E0%A5%88%E0%A4%82" has 9 occurrences, we can require that only 9 consecutive sequences of % with two characters should be matched.

const res = decodeURIComponent(encodeURIComponent("हैंहैंI")
.match(/(\%[A-F0-9]{2}){9}|./g)
.reverse().join(''))

console.log(res);

Test cases:

function reverse(str) {
  return decodeURIComponent(encodeURIComponent(str)
    .match(/(\%[A-F0-9]{2}){9}|./g)
    .reverse().join(''))
}

console.log(reverse("हैंI"))
console.log(reverse("AहैंI"))
console.log(reverse("IAहैं"))
console.log(reverse("हैंहैंI"))
console.log(reverse("ABहैंहैंIA"))
console.log(reverse("ABहैंIU90QहैंIA"))

---

I also attempted this logic, but reversing the characters after the map gave the wrong result. However, I'm positive that this method could eventually work well if there was a way of capturing the special character automatically instead of manually (see last example).

Using String#fromCodePoint

const res1 = String.fromCodePoint(...[..."हैंI"].map(c=>c.charCodeAt()));

const res2 = String.fromCodePoint(...[..."हैंI"].map(c=>c.charCodeAt()).reverse());

console.log(res1, res2);

//however it works when they are put in the right order
const arr = [..."हैंI🌷"]
.map(c=>c.codePointAt())
.filter(a=>a!==undefined);

console.log(arr);
const res = String.fromCodePoint(...arr.splice(arr.length-1,1), ...arr)
console.log(res);
