I wish this help you You might want to use a HashSet to store the string you already have since the access is way faster. Then remove all the characters you don't want in the string:
code :
static String beautify(String ugly)
{
    return String.Join("", ugly.Where(c => Char.IsLetter(c)));
}
static HashSet<String> lines = new HashSet<String>();
static List<String> input = new List<String>()
{
    "hello world","hello, world","hello, world.",".hello, world",
};

static void Main(String[] args)
{
    initList(input);
    var tests = new List<String>() {
        "h,e.l!l:o. w----orl.d.",// True
        "h,e.l!l:o. w----ol.d.",// False

    };

    foreach(var test in tests)
    {
        Console.WriteLine($"The string \"{test}\" is {(lines.Contains(beautify(test)) ? "already" : "not" )} here"); 
    }

    Console.ReadLine();
}

static void initList(List<String> input)
{
    foreach(String s in input)
        lines.Add(beautify(s));
}

static String beautify(String ugly)
{
    return String.Join("", ugly.Where(c => Char.IsLetter(c)));
}
lines
Count = 4
    [0]: "hello world"
    [1]: "hello, world"
    [2]: "hello, world."
    [3]: ".hello, world"
lines.Contains("hello, world.")
true
lines.Contains("hello, world..")
false

Any of those help hello-world how are you? , You can use this regex for splitting:
code :
String str = "hello-world how are you?";
Arrays.stream(str.split("\\p{javaWhitespace}+|(?=\\p{P})|(?<=\\p{P})")).forEach(System.err::println);
hello
-
world
how
are
you

Hope this helps You can use std::any_of and std::ispunct.
When using something like std::any_of or std::find_if the easiest thing to do is to pass it a lambda.
code :
#include <iostream>
#include <algorithm>
#include <cctype>

int main() {
    std::string str = "fdsfd/jl";

    if (std::any_of(str.begin(), str.end(), [](char c){ return std::ispunct(c); } ))
        std::cout << "PUNCT!";
    return 0;
}

it fixes the issue The general strategy to preserve text while also splitting on it at the same time is to use lookarounds. Lookarounds assert logic, but do not actually consume any text. They are basically zero width. I split below using the pattern:
code :
(?=[\\.,!;?:\"])|(?<=[\\.,!;?:\"])
String sentence = "hello, What you are doing?How are you?";
String[] parts = sentence.split("(?=[\\.,!;?:\"])|(?<=[\\.,!;?:\"])");
for (String part : parts) {
   System.out.println(part);
}

hello
,
 What you are doing
?
How are you
?

I wish this helpful for you The main issue is that you're modifying letter_set while iterating over it. This does not work as expected (explanation).
To fix, iterate over a copy:
code :
for char in letter_set[:]:
