help you fix your problem Use Spread syntax.
code :
let code = [104,101,108,108,111,32,119,111,114,108,100];

console.log(String.fromCharCode(...code));

How to convert a C string (char array) into a Python string when there are non-ASCII characters in the string?

How to convert a C string (char array) into a Python string when there are non-ASCII characters in the string?

wish helps you I have embedded a Python interpreter in a C program. Suppose the C program reads some bytes from a file into a char array and learns (somehow) that the bytes represent text with a certain encoding (e.g., ISO 8859-1, Windows-1252, or UTF-8). How do I decode the contents of this char array into a Python string? , PyString_Decode does this:
code :
PyObject *PyString_Decode(const char *s,
              Py_ssize_t size,
              const char *encoding,
              const char *errors)
{
    PyObject *v, *str;

    str = PyString_FromStringAndSize(s, size);
    if (str == NULL)
    return NULL;
    v = PyString_AsDecodedString(str, encoding, errors);
    Py_DECREF(str);
    return v;
}
#include <Python.h>
#include <stdio.h>

int main(int argc, char *argv[])
{
     char c_string[] = { (char)0x93, 0 };
     PyObject *py_string, *py_unicode;

     Py_Initialize();

     py_string = PyString_FromStringAndSize(c_string, 1);
     if (!py_string) {
          PyErr_Print();
          return 1;
     }
     py_unicode = PyString_AsDecodedObject(py_string, "windows_1252", "replace");
     Py_DECREF(py_string);

     return 0;
}

I wish this helpful for you You need to turn it into a corresponding byte array and then instantiate new String(byteArray).
code :
String [] strings = input.substring(1, input.length()-1).split(",");
byte[] bytes = new byte[strings.length];
int i = 0;
for (String s : strings) bytes[i++] = Byte.parseByte(s);
System.out.println(new String(bytes, "UTF-8"));

I hope this helps you . You can use Array#pack:
code :
["666f6f626172"].pack('H*')
#=> "foobar"

help you fix your problem I want to remove all characters with ascii codes 32 - 47 and some more from string. Exactly !"#$%&'()*+,-./\~. , To use the characters just include them in a character class:
code :
$string = preg_replace(':[\s!"#$%&\'()*+,-./\\\~]:', '', $string);
[\x20-\x2f\x5c\x7e]
[ -/\\\~]
