Replaces PR #4281.
When changing the console output code page, check whether the current
font can support it. If not, try to find a suitable font for the new
code page. If none can be found:
- if we are creating a new console, forcefully switch to codepage 437
(OEM USA) and retry finding a font, falling back to "Terminal" if
none could be found;
- if we were just changing the current CP, just fail and keep the old
code page and font.
Rework the console font selection/creation functions for this new job
(see CreateConsoleFontEx() and friends). Elements of implementation
based from https://github.com/microsoft/terminal ; see code for more
information.
Silence the noisy IsValidConsoleFont2() diagnostic messages.
Add Doxygen documentation.
[CONSOLE.CPL] Only add "Terminal" to the enumerated list of faces
+ add a TODO implementation comment.
- Update the documentation of members of CONSOLE_INPUT_BUFFER.
- Simplify ConDrvGetConsoleNumberOfInputEvents().
- Simplify ConDrvFlushConsoleInputBuffer().
- Use also GetConsoleInputBufferMode() more often.
Far-East Asian language (Chinese, Japanese and Korean; CJK) needs special handling in console.
Especially a fullwidth character (mk_wcwidth_cjk(ch) == 2) needs a double width space. A fullwidth character on the console window is treated as a pair of a leading byte and a trailing byte (COMMON_LVB_LEADING_BYTE and COMMON_LVB_TRAILING_BYTE). CORE-12451
Make preparation for console support of Chinese, Japanese and Korean (CJK) codepages. CORE-12451
- Add consrv/frontends/wcwidth.c.
- Add GuiPaintTextModeBufferCJK function.

- CONSOLE: Initialize the additional TrueType fonts cache.
* Fix the font preview when a TrueType font has been selected.
* Refresh the available fonts and the font preview when the selected
code page is changed (Work In Progress), or when the OS pool of
font resources has changed (WM_FONTCHANGE message).
- CONCFG: Implement support for the additional TrueType fonts cache:
the contents of the cache is enumerated under the registry key
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Console\TrueTypeFont
* Add helper functions and macros.
* In CreateConsoleFontEx(), set the mandatory font pitch&family flags
and remove those that we do not support.
* In IsValidConsoleFont2(), update the validity checks and the
documentation links.
- CONSRV: Load/refresh the additional TrueType fonts cache when needed.
