Is 0x9B (155decimal) a special control character? Why is it missing from ascii tables?

I think the issue was by ths following , In ANSI escape sequences, 0x9B is the one-character Control Sequence Introducer (the multi-character version which is more familiar is ESC-[.

Can't print ascii 121 to character y, instead printing a special character

Can't print ascii 121 to character y, instead printing a special character

I wish did fix the issue. Your code is working as intended. Here an online compiler with a few added debug-lines.
As you can see, it will find 127 for the character y (121) in the input, being the first greater prime. The ASCII character with code-point 127 is an unprintable character however, which makes it appear as if there isn't a character in the output.
code :
if ((temp - lowerPrime) == (greaterPrime - temp)) {
    b[k] = lowerPrime;
} else if ((temp - lowerPrime) < (greaterPrime - temp)) {
    b[k] = lowerPrime;
} else if ((temp - lowerPrime) > (greaterPrime - temp)) {
    b[k] = greaterPrime;
}
if ((temp - lowerPrime) <= (greaterPrime - temp)) { // Single <=, instead of loose == and <
    b[k] = lowerPrime;
} else if ((temp - lowerPrime) > (greaterPrime - temp)) {
    b[k] = greaterPrime;
}

I wish this help you I tried this code to capitalize each non-ascii character or simple letter in a string after a space or a special character like "-", but it doesn't work : , You may use
code :
console.log(
    "jean-àris-sa ça".replace(/(-|\s+|^)(.)/g, function(_,$1,$2) { 
       return $1 + $2.toUpperCase(); 
    } )
)
var regex = XRegExp("(\\pL)(\\pL*)");
console.log( XRegExp.replace("jean-àRiS-sa çA", regex, function(_, $1, $2) {
      return $1.toUpperCase()  + $2.toLowerCase();
   }, "all")
);
<script src="https://cdnjs.cloudflare.com/ajax/libs/xregexp/3.2.0/xregexp-all.min.js"></script>
console.log( 
   "jean-àRiS-sa çA".replace(/(\p{L})(\p{L}+)/gu, 
         (_, $1, $2) => $1.toUpperCase()  + $2.toLowerCase())
);

may help you . I am using the notalnum function in SAS. The input is a db field. Now, the function is returning a value that tells me there is a special character at the end of every string. It is not a space character, because I have used COMPRESS function on the input field. , The $HEX. format is the easiest way to see what they are:
