 				When printing to standard output, the supported subset of BBCode is converted to ANSI escape codes for the terminal emulator to display. Support for ANSI escape codes varies across terminal emulators, especially for italic and strikethrough. In standard output, [code]code[/code] is represented with faint text but without any font change. Unsupported tags are left as-is in standard output.
