Alastair Houghton	fb1211e3fa	Rename the functions as they're exported as C APIs. ... `SWIFT_RUNTIME_STDLIB_INTERNAL` does `extern "C"`, so we can't put these in a namespace and have to use a C-style prefix instead. Also slightly rearrange the code in `CommandLine.cpp`. rdar://103397975	2022-12-21 11:44:37 +00:00
Alastair Houghton	ca771c4d1d	Change to returning nullptr rather than triggering a fatal error. ... Instead of triggering a fatal error on failure, return `nullptr` and let the caller decide what to do about it. The CommandLine code should trigger a fatal error, of course. rdar://103397975	2022-12-21 11:44:37 +00:00
Alastair Houghton	a31b1c54fa	Centralise code to map between UTF-8 and UTF-16 on Windows. ... In various places we need to call the Windows API, and because Swift uses UTF-8 for its string representation, we can’t call the ANSI API functions (because the code page used for the ANSI functions varies depending on the system locale setting). Instead, we need to use the wide character APIs. This means that we need to convert UTF-8 to wide character and vice-versa in various places in the runtime. rdar://103397975	2022-12-21 11:44:35 +00:00
