is there something similar to std::quote for multiple characters like ETX/STX pairs

Question

I see there is a function in <iomanip> for quoting a single char out and in a std::string. I search something similar to that for multiple characters. My current use case is to masquerade STX / ETX pairs in/out a string.

Use for std::quote is easy like:

std::string example{ "Hallao" };
std::cout << std::quoted(example, 'a', 'x') << std::endl;

So my wish to see is something like:

std::cout << std::quoted(example, {0x02,0x03}, ...) << std::endl;

Is that already done somewhere or is this to special to be a part of STL?

Answer 1

Unfortunately, so far there isn't. The delim and escape chars are restricted to one character. You can't use multiple chars or string under the current interface.

This unnecessary limitation applies to a lot of components too :( (for example the isalpha family of functions)
