It will always fail if redirected. We can test the conditions using:
pg_ctl start > result.log
So, the comment should be:
/* WriteConsoleW always fails if stderr is redirected. */
I cleaned up the patch per comments. I hope this will be the final one ;-).
* Use in_error_recursion_trouble() instead of own implementation.
* Use def_enc2name() macro to avoid adding the codepage field
on non-win32 platforms.
* Fix a bug of calculation of result length.
* Fix a memory leak on error handling path in pgwin32_toUTF16().

Sure, the logfile will be filled with mixed encoding strings,
that could happen in logfile and syslog on non-win32 platforms.
I think UTF8 is better than UTF16 for logfile encoding because
there are some text editors that do not support wide characters.
At any rate, the logfile encoding feature will come from another patch,
that might add "log_encoding" variable and work on any platforms.
