计算外语中的字符数 [英] Count number of characters present in foreign language

问题描述

是否有任何最佳方式来实现非英文字母的字符数？例如，如果我们用英语中的母亲这个词，它就是一个6个字母的单词。但是如果你在泰米尔语中键入相同的单词（மதர்），它是一个三个字母的单词（ம+த+ர்），但最后一个字母（ர்）将被系统视为两个字符（ர+ஂ=ர்）。那么有没有办法计算真实角色的数量？

Is there any optimal way to implement character count for non English letters? For example, if we take the word "Mother" in English, it is a 6 letter word. But if you type the same word(மதர்) in Tamil, it is a three letter word(ம+த+ர்) but the last letter(ர்) will be considered as two characters(ர+ஂ=ர்) by the system. So is there any way to count the number of real characters?

一个线索是，如果我们将键盘中的光标移动到单词（மதர்）中，它将仅通过3个字母，而不是系统考虑的4个字符，那有没有办法通过使用这个来找到解决方案？任何有关这方面的帮助将不胜感激......

One clue is that if we move the cursor in keyboard into the word (மதர்), it will pass through 3 letters only and not into 4 chars considering by the system, so is there any way to find the solution by using this? Any help on this would be greatly appreciated...

我担心之前的语言不能用任何外语这么好用
所以我添加了另一个小提琴可能的方式

Update

Back from lunch =) I'm afraid that the previous won't work this well with any foreign language So i added another fiddle with a possible way

var UnicodeNsm = [Array 1280] //It holds all escaped Unicode Non Space Marks
function countNSMString(str) {
    var chars = str.split("");
    var count = 0;
    for (var i = 0,ilen = chars.length;i<ilen;i++) {
      if(UnicodeNsm.indexOf(escape(chars[i])) == -1) {
        count++;
       }
    }
    return count;
}

var English = "Mother";  
var Tamil = "மதர்";
var Vietnamese = "mẹ"
var Hindi = "मां"

function logL (str) {    
      console.log(str + " has " + countNSMString(str) + " visible Characters and " + str.length + " normal Characters" ); //"மதர் has 3 visible Characters"
}

logL(English) //"Mother has 6 visible Characters and 6 normal Characters"
logL(Tamil) //"மதர் has 3 visible Characters and 4 normal Characters"
logL(Vietnamese) //"mẹ has 2 visible Characters and 3 normal Characters"
logL(Hindi) //"मां has 1 visible Characters and 3 normal Characters"

所以这只是检查字符串中的任何字符是否是Unicode NSM字符并忽略对于这个，这个应该适用于大多数语言，而不仅仅是泰米尔语，
和一个包含1280个元素的数组不应该是性能问题那么大

So this just checks if theres any Character in the String which is a Unicode NSM character and ignores the count for this, this should work for the Most languages, not Tamil only, And an array with 1280 Elements shouldn't be that big of a performance issue

在尝试使用字符串操作后，结果是
String.indexOf 返回

After experimenting a bit with string operations, it turns out String.indexOf returns the same for

ர்和ர
含义

ர்ரர.indexOf（ர்）== ர்ரர.indexOf（ர+்）// true 但是

ர்ரர.indexOf（ர）== ர்ரர.indexOf（ர+ர） // false

"ர்" and for "ர" meaning
"ர்ரர".indexOf("ர்") == "ர்ரர".indexOf("ர" + "்") //true but
"ர்ரர".indexOf("ர") == "ர்ரர".indexOf("ர" + "ர") //false

我抓住这个机会尝试过这样的事情

I took this opportunity and tried something like this

//ர்

var char = "ரர்ர்ரர்்";
var char2 = "ரரர்ர்ரர்்";    
var char3 = "ர்ரர்ர்ரர்்";

function countStr(str) {
         var  chars = str.split("");
         var count = 0;
          for(var i = 0, ilen = chars.length;i<ilen;i++) {
                 var chars2 = chars[i] + chars[i+1];   
                 if (str.indexOf(chars[i]) == str.indexOf(chars2))
                   i += 1;
               count++;
            }
         return count;
 }


console.log("--");

console.log(countStr(char)); //6

console.log(countStr(char2)); //7

console.log(countStr(char3)); //7

这似乎适用于上面的字符串，可能需要一些调整，因为我不喜欢不知道关于编码和东西的事情，但也许你可以开始点

Which seems to work for the String above, it may take some adjustments, as i don't know a thing about Encoding and stuff, but maybe its a point you can begin with
