Windows CLI arguments use either ANSI (main()) or UTF-16 (wmain()).
Meanwhile, Ceph libraries expect UTF-8 and raise exceptions when
trying to use Unicode CLI arguments or log Unicode output:
rbd.exe create test_unicode_șțăâ --size=32M
terminate called after throwing an instance of 'std::runtime_error'
what(): invalid utf8
We'll use a Windows application manifest, setting the "activeCodePage"
property [1][2]. This enables the Windows UCRT UTF-8 mode so that
functions that receive char* arguments will expect UTF-8 instead of ANSI,
including main(). One exception is CreateProcess, which will need the
UTF-16 form (CreateProcessW).
Despite the locale being set to utf-8, we'll have to explicitly set
the console output to utf-8 using SetConsoleOutputCP(CP_UTF8).
In order to use the UTF-8 locale, we'll have to switch the mingw-llvm
runtime from msvcrt to ucrt.
This also fixes ceph-dokan crashes that currently occur when non-ANSI
paths are logged.

# This script expects the following variables:

# * OS - currently ubuntu, rhel, or suse. In the future we may attempt to

# * MINGW_CMAKE_FILE - if set, a cmake toolchain file will be created

# * USE_MINGW_LLVM - allows using the mingw llvm toolchain
|
