X-Received-From: 2607:f8b0:4864:20::72f Subject: [Qemu-devel] [PULL 01/24] qga: Support Unicode paths in guest-file-open on win32 X-BeenThere: qemu-devel@nongnu.org X-Mailman-Version: 2.1.21 Precedence: list List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Cc: Jonathon Reinhart , peter.maydell@linaro.org Errors-To: qemu-devel-bounces+importer=patchew.org@nongnu.org Sender: "Qemu-devel" X-ZohoMail-DKIM: fail (Header signature does not verify) Content-Transfer-Encoding: quoted-printable MIME-Version: 1.0 Content-Type: text/plain; charset="utf-8" From: Jonathon Reinhart Currently, the win32 port of QEMU Guest Agent does not properly handle Unic= ode paths. The JSON decoder produces a valid UTF-8 path string, but this is pas= sed directly to CreateFileA, which is expecting an ANSI string and not UTF-8. T= his leads to mangled filenames. This patch follows the example of qmp_guest_set_user_password() and uses g_utf8_to_utf16() to convert the string to UTF-16 and calls CreateFileW() explicitly.
