Although there is no concrete case where we use the (nhdr + length),

Note that for this LTS version we now print g10 Code as the first
copyright holder with --version.  This is to avoid confusion at our
customers, now that we also provide a Linux^WGNU/Linux version of

common: Fix creation of Windows socket directories.
* common/homedir.c (w32_try_mkdir): Remove.
(standard_homedir): Use gnupg_mkdir instead of w32_try_mkdir.
(_gnupg_socketdir_internal): Ditto.
--

The w32_try_mkdir was once introduced for WindowsCE and unfortunately
at a too brief inspection it looks like it does the utf8->wchar
conversion.  Which it does not.  Thus I obviously never tested the
switch to from APPDATA to LOCAL_APPDATA with a non-ascii account name.
That might have been due to the use of the very same code for the
homedir - but there is other code in gpg to create the homedir; thus a
failure here is mostly fixed later.

The missing error diagnostic was - and is - on purpose to avoid such
error messages due to a race between several running gpg instances.

# gpgconf.ctl
#
# This file is used to change the directories where the gpg components

# variables are substituted in standard shell manner, the final value
# must start with a slash, trailing slashed are stripped.

--

This fixes a bug with user ids with leading spaces because:

wks-client lists all mail addresses from the key and matches them to the
requested mail address.

If there are several user-ids all with the same mail address
wks-client picks one of them and then extracts exactly that user id.
However, here it does not match by the mail address but by the full
user-id so that we can be sure that there will be only one user-id in
the final key.

The filter built expression unfortunately strips leading blanks but
requires a verbatim match.  Thus it won't find the user id again and
errors out.

The new -t flag and a non-trimming strtokenize solves the problem.

That is actually a more correct directory than APPDATA.  This fixes
a problem with installations where the APPDATA is non a network drive
and the resulting socket filename is truncated in our socket helper
function (because we use sockaddr also for our local socket
emulation on Windows).

LOCAL_APPDATA is expected to be on the local box and thus in the
majority of cases the resulting socket file name will be short enough.

To test this switch the Windows Console to "legacy mode"

Windows versions (and the legacy console) don't have a proper font
installed for this.  Without this patch this runs into a log_fatal

The mitigation we implement is to fallback to WriteConsoleA, that is
accepting wrong encoding and to print a note about the problem.

w32: Always use Unicode for console input and output.
* common/init.c (_init_common_subsystems) [W32]: Set the codepage to
UTF-8 for input and putput.  Switch gettext to UTF-8.
* g10/gpg.c (utf8_strings) [W32]: Make sure this is always set.

With this patch the former patch to use ReadConsoleW and WriteConsoleW
in ttyio.c are kind of superfluous because the ANSI version of these
functions are also able to read/write UTF-8 directly given the console
code page has been set correctly.  However, this seems to work only
with recent versions of Windows-10.

common,w32: Allow Unicode input and output with the console.
* common/ttyio.c (do_get) [W32]: Use ReadConsoleW.
(w32_write_console): New.
(tty_printf, tty_fprintf) [W32]: Use new function.
--

Note that due this change fixed stings (i.e. gettext translations)
printed to the console will not be rendered correctly unless "chcp
65001" has been used.  This needs to be fixed by followup patch.
