Unicode console

Small class that makes console input/output with utf-8 easier in c++17.

Usage

Read (UTF-8 string) from console

auto const input = unicode_console::read<std::string>();

Or:

std::string input;
unicode_console::io >> input

Read a line of UTF-8 text from console

auto const input = unicode_console::readln();

Write to console

unicode_console::println("Here is a little unicode: åäö ÿëã")
        .println("And a number: ", 1234);

Or:

unicode_console::io << "Here is a little unicode: åäö ÿëã\n" 
            << "And a number: " << 1234 << '\n';

Validate input from console

Only validate type (for numbers)

auto const input = unicode_console::read_validated<double>("That's not a number! Try again.");

Custom validation + type validation with single error message

// input should be between -3.14 and 3.14
auto const input = unicode_console::read_validated<double>(
    [](auto const input) {
        return input > -3.14 && input < 3.14;
    }, 
    "Invalid input! Try again."
);

Custom validation + type validation with separate error messages

// input should be between -3.14 and 3.14
auto const input = unicode_console::read_validated<double>(
    [](auto const input) {
        return input > -3.14 && input < 3.14;
    }, 
    "That's outside of the range! Try again.",
    "That's not a number!"
);
