# Example

```cpp

#include 

#include 

int main()

{

    std::cout << std::boolalpha

        << charimpl::is_ascii() << std::endl

        << charimpl::is_ebcdic() << std::endl

        << charimpl::is_ebcdic037() << std::endl

        << charimpl::is_ebcdic1047() << std::endl;

}

```

# 

All functions are marked as consteval/constexpr and noexcept if allowed by the compiler.

```c++

bool charimpl::is_ascii(); // Returns true if ASCII encoding is currently in use, false otherwise

bool charimpl::is_ebcdic(); // Returns true if any form of EBCDIC encoding is currently in use, false otherwise

bool charimpl::is_ebcdic037(); // Returns true if EBCDIC037/IBM037 encoding is currently in use, false otherwise

bool charimpl::is_ebcdic273(); // Returns true if EBCDIC273/IBM037 encoding is currently in use, false otherwise

bool charimpl::is_ebcdic1047(); // Returns true if EBCDIC1047/IBM1047 encoding is currently in use, false otherwise

```

```c++

CHARIMPL_ASCII_EXPR // Macro which expands to an expression equal to the result of charimpl::is_ascii()

CHARIMPL_EBCDIC_EXPR // Macro which expands to an expression equal to the result of charimpl::is_ebcdic()

CHARIMPL_EBCDIC037_EXPR // Macro which expands to an expression equal to the result of charimpl::is_ebcdic037()

CHARIMPL_EBCDIC273_EXPR // Macro which expands to an expression equal to the result of charimpl::is_ebcdic273()

CHARIMPL_EBCDIC1047_EXPR // Macro which expands to an expression equal to the result of charimpl::is_ebcdic1047()

```

*Note: Macros should be surrounded with parentheses when used in larger statements in order to avoid potential issues with operator precedence*
