-Test program demonstrating a problem in Windows 15048's ReadConsoleOutput API.
-
-To compile:
-
- cl /nologo /EHsc winbug-15048.cc shell32.lib
-
-Example of regressed input:
-
-Case 1:
-
- > chcp 932
- > winbug-15048 -face-gothic 3044
-
- Correct output:
-
- 1**34 (nb: U+3044 replaced with '**' to avoid MSVC encoding warning)
- 5678
-
- ReadConsoleOutputW (both rows, 3 cols)
- row 0: U+0031(0007) U+3044(0107) U+3044(0207) U+0033(0007)
- row 1: U+0035(0007) U+0036(0007) U+0037(0007) U+0038(0007)
-
- ReadConsoleOutputW (both rows, 4 cols)
- row 0: U+0031(0007) U+3044(0107) U+3044(0207) U+0033(0007) U+0034(0007)
- row 1: U+0035(0007) U+0036(0007) U+0037(0007) U+0038(0007) U+0020(0007)
-
- ReadConsoleOutputW (second row)
- row 1: U+0035(0007) U+0036(0007) U+0037(0007) U+0038(0007) U+0020(0007)
-
- ...
-
- Win10 15048 bad output:
-
- 1**34
- 5678
-
- ReadConsoleOutputW (both rows, 3 cols)
- row 0: U+0031(0007) U+3044(0007) U+0033(0007) U+0035(0007)
- row 1: U+0036(0007) U+0037(0007) U+0038(0007) U+0000(0000)
-
- ReadConsoleOutputW (both rows, 4 cols)
- row 0: U+0031(0007) U+3044(0007) U+0033(0007) U+0034(0007) U+0035(0007)
- row 1: U+0036(0007) U+0037(0007) U+0038(0007) U+0020(0007) U+0000(0000)
-
- ReadConsoleOutputW (second row)
- row 1: U+0035(0007) U+0036(0007) U+0037(0007) U+0038(0007) U+0020(0007)
-
- ...
-
- The U+3044 character (HIRAGANA LETTER I) occupies two columns, but it only
- fills one record in the ReadConsoleOutput output buffer, which has the
- effect of shifting the first cell of the second row into the last cell of
- the first row. Ordinarily, the first and second cells would also have the
- COMMON_LVB_LEADING_BYTE and COMMON_LVB_TRAILING_BYTE attributes set, which
- allows winpty to detect the double-column character.
-
-Case 2:
-
- > chcp 437
- > winbug-15048 -face "Lucida Console" -h 4 221A
-
- The same issue happens with U+221A (SQUARE ROOT), but only in certain
- fonts. The console seems to think this character occupies two columns
- if the font is sufficiently small. The Windows console properties dialog
- doesn't allow fonts below 5 pt, but winpty tries to use 2pt and 4pt Lucida
- Console to allow very large console windows.
-
-Case 3:
-
- > chcp 437
- > winbug-15048 -face "Lucida Console" -h 12 FF12
-
- The console selection system thinks U+FF12 (FULLWIDTH DIGIT TWO) occupies
- two columns, which happens to be correct, but it's displayed as a single
- column unrecognized character. It otherwise behaves the same as the other
- cases.
