How to Print UTF-8 Characters in Windows Console

When using the Windows console, it can be challenging to display Unicode characters properly. Here's how to address this issue:

By default, wide print functions in Windows do not handle non-ASCII Unicode characters. To enable their correct display, you can adopt one of these approaches:

Using the Console API Directly:

Use the WriteConsoleW function to write Unicode data directly to the console. Ensure you're writing to a console handle and use alternative methods for non-console targets.

Setting File Descriptor Mode:

Set the standard output file descriptor mode to either _O_U16TEXT or _O_U8TEXT. This ensures Unicode data is correctly output to the Windows console. Note that non-wide character functions become unusable after setting these modes.

Setting Console Output Codepage to CP_UTF8:

Set the console output codepage to CP_UTF8 and use appropriate functions. Higher-level functions may not work correctly in this scenario, so use lower-level functions or create a custom ostream implementation.

Handling Multibyte Characters:

Unlike other operating systems, Windows consoles have a unique behavior when handling multibyte characters. Each byte must be written separately, and not as a continuous stream. This requires implementing your own streambuf subclass that maintains conversion state and handles multibyte character encoding correctly.

By implementing one of these methods, you can successfully display UTF-8 characters in the Windows console, ensuring the proper representation of non-ASCII Unicode characters.
