I'm trying to make a Unicode Converter from UTF-8 to UTF-16, but I want to only convert strings and objects and stuff like that in JSON, not the structure of JSON because that would make it unreadable to programs.
Entered UTF-8:
{
"hi":{
"this":["is","just","some","example"]
}
}
Expected UTF-16:
{
"\u0068\u0069":{
"\u0074\u0068\u0069\u0073":["\u0069\u0073","\u006a\u0075\u0073\u0074","\u0073\u006f\u006d\u0065","\u0065\u0078\u0061\u006d\u0070\u006c\u0065"]
}
}
Can anyone help? Also, I'm pretty new to Javascript, so don't be too harsh.
This is a pretty good way to do what you need:
let json_string = '{ "hi": {"this": ["is", "just", "some", "example"]}}'
function encode_to_utf16(x) {
var res = "";
for (var i = 0; i < x.length; i++) res+= "\\u" + ("000" + x[i].charCodeAt(0).toString(16)).substr(-4);
return res;
}
// get all the values present between the double quotes
let arr = json_string.match(/"[^"]+"/gi)
arr.forEach((str)=>{
// replace double quotes with empty string
str = str.replace(/"/gi,"");
// encode and replace them
json_string = json_string.replace(str,encode_to_utf16(str))
})
console.log(json_string)However, if there is a double quote with escape character (\") somewhere in a string, then this'll break down. Maybe, you can improvise on that.
