// when the cursor advances beyond the last row in the console screen buffer. If this mode is

// When writing with WriteFile or WriteConsole, this adds an additional state to end-of-line
// wrapping that can delay the cursor move and buffer scroll operations.
//
// Normally when ENABLE_WRAP_AT_EOL_OUTPUT is set and text reaches the end of the line, the
// cursor will immediately move to the next line and the contents of the buffer will scroll up
// by one line. In contrast with this flag set, the cursor does not move to the next line, and
// the scroll operation is not performed. The written character will be printed in the final
// position on the line and the cursor will remain above this character as if
// ENABLE_WRAP_AT_EOL_OUTPUT was off, but the next printable character will be printed as if
// ENABLE_WRAP_AT_EOL_OUTPUT is on. No overwrite will occur. Specifically, the cursor quickly
// advances down to the following line, a scroll is performed if necessary, the character is
// printed, and the cursor advances one more position.
//
// The typical usage of this flag is intended in conjunction with setting
// ENABLE_VIRTUAL_TERMINAL_PROCESSING to better emulate a terminal emulator where writing the
// final character on the screen (../in the bottom right corner) without triggering an
// immediate scroll is the desired behavior.

// The APIs for writing character attributes including WriteConsoleOutput and
// WriteConsoleOutputAttribute allow the usage of flags from character attributes to adjust the
// color of the foreground and background of text. Additionally, a range of DBCS flags was
// specified with the COMMON_LVB prefix. Historically, these flags only functioned in DBCS code
// pages for Chinese, Japanese, and Korean languages.
//
// With exception of the leading byte and trailing byte flags, the remaining flags describing
// line drawing and reverse video (../swap foreground and background colors) can be useful for
// other languages to emphasize portions of output.
//
// Setting this console mode flag will allow these attributes to be used in every code page on
// every language.
//
// It is off by default to maintain compatibility with known applications that have
// historically taken advantage of the console ignoring these flags on non-CJK machines to
// store bits in these fields for their own purposes or by accident.
//
// Note that using the ENABLE_VIRTUAL_TERMINAL_PROCESSING mode can result in LVB grid and
// reverse video flags being set while this flag is still off if the attached application
// requests underlining or inverse video via Console Virtual Terminal Sequences.
