Some additional explanation:

CreateNamedPipe is not affected by this bug and works fine if such name is
passed to it.
But CreateFile fails because its name checking should handle different types of
objects, not only pipes. The checking itself is done in
wine_nt_to_unix_file_name(). Call path is

wine_nt_to_unix_file_name() should return STATUS_BAD_DEVICE_TYPE, which is then
returned by nt_to_unix_file_name_attr(). This return status causes
FILE_CreateFile to perform an "open_file_object" server request, that opens
pipe object.

Previously, because of checking for illegal characters performed by
wine_nt_to_unix_file_name(), wine_nt_to_unix_file_name() returned
STATUS_OBJECT_NAME_INVALID, that caused error while opening pipe.

This patch modifies wine_nt_to_unix_file_name() to not check pipe name for
special characters and doesn't affect any objects except pipes.
