can't decode base64-encoded data with linebreaks

[a1021101652]

Can't remove '\n' directly at here ,because of the character not in standard base64-encoded data ,but i don't know better solution

issue at :base64.cpp:171
`
if (remove_linebreaks) {

   std::string copy(encoded_string);

   copy.erase(std::remove(copy.begin(), copy.end(), '\n'), copy.end());

   return base64_decode(copy, false);
}`

Windows linefeed is \r\n
Old MacOS linefeed is \r. New MacOS versions is \n
Linux linefeed is \n.

To avoid errors on decode, try removing all spacing chars \r, \n, \t, \v, \f, \000

Example

#include <string>
#include <iostream>
#include <vector>

void removeSubstrings(std::string& str, const std::vector<std::string>& toRemove) {
    for (const auto& subStr : toRemove) {
        size_t pos;
        while ((pos = str.find(subStr)) != std::string::npos) {
            str.erase(pos, subStr.length());
        }
    }
}

int main() {
    std::string str = "String\n with\t text\r that must be removed 😑😀!!!";
    std::vector<std::string> toRemove = {"\r", "\n", "\t", "😑"};

    removeSubstrings(str, toRemove);

    std::cout << "Result: " << str << std::endl;

    return 0;
}

Output

Result: String with text that must be removed 😀!!!
