What is your opinion of the proposed patch to just this interface?
It seems
that aligning to the system LCID is very problematic for a
multi-user OS,
where you are on an eastern European codepage, and I'm on a western
codepage.
The files you are working with are likely different than mine.
Changing to
the systemwide codepage definitely seems invalid, notwithstanding
the issues
noted about apr_user_name_get().
Anyway, we're not ignoring the whole thread locale here — just the
code page part. And here's another thought experiment: Notepad, by
default, saves and reads files in the system codepage, regardless of
what the user locale says. Makes sense to be compatible with Notepad,
doesn't it? 8=] That, and apr_user_name_get, and all the ANSI versions
of the WinAPI functions - you'd be hard-pressed to find a place where
the user locale's code page is actually used. Well, maybe in projects
that use APR. 8=]
I was under the impression that Windows allowed each window of each
application to use a different input method and code page, hence the
assumption that the thread locale's code page is the correct one. Is
that not the case?
The input method, AFAIK, is thread-specific, but it's largely irrelevant
here. "Code page", on the other hand... An application can in principle
use any code page it wants, but the ANSI WinAPI functions definitely use
the system locale's ANSI codepage, a.k.a. CP_ACP, GetACP(), and
GetLocaleInfo(LOCALE_SYSTEM_DEFAULT, LOCALE_IDEFAULTANSICODEPAGE). See the
link in my first post (and try the Notepad experiment). Since the ANSI
codepage is all the Unicode-unaware apps get, they naturally tend to
produce and consume CP_ACP-flavoured text; and since Unicode-aware apps
want to stay compatible with the unaware, they tend to do that, as well.
