[UWP]UTF-8 AppxManifest.xml file missing BOM

Question

It's about VS2015 create Windows 10 UAP package.

We know in windows, when parse utf8 text, need 3 bytes header( EF BB BF) at the front of all bytes. If it don't exits, and

the text contains some none-ACSII character, the parsing will take some wrong result!

But!!!! When we use VS2015 to create Windows 10 UAP package, the file "AppxManifest.xml" in the *.appx or other package

format(not in the Release folder)(use WinRAR to open it), the 3 bytes had been removed by someone!!! It cause all None-

English app(if the app name or somewhere contains none-ACSII character) break!!!!!

Why the file "AppxManifest.xml" in the Release folder is correct, but in the package is wrong?! Who did it on purpose??

should your fire this man??

Hello WYB,

1. Are you using Chinese version of visual studio?

2. How are you checking the headers?

3. Can you please provide sample demo in which we can reproduce this issue so we can check it out what is causing this?

1. Yes, VS2015 Chinese version.

2. After created AppStore package, use WinRAR to open the "xxx.appxupload" file, and then double click the "xxx.appxbundle" file in it, WinRAR will open this file, and double click the file like "xxx.appx", you'll see "AppxManifest.xml", drop it out, use tool like "Binary Viewer", you can see it lost the UTF8 header which: "EF BB BF".

3. Create any Windows10 app, you'll see it.

But I'll say sorry to you, the lost of UTF8 header don't cause my problem, When I add all size of Tile and SplashScreen, it works!! But I feel a little sad, because VS2015 never tells me a clear message!!

When I update the "Windows10 uap pack tool" from 1.0 to 1.1 in VS 2015, Oh, all project which created by Unity3d 5.2.0 can't pack appxupload file any more!! It cause a exception like: "AppxManifest referenced a file 'xxx.dll' which is not exits in payload". All my friends who update the "Windows10 uap pack tool" from 1.0 to 1.1 in VS 2015 bring this same exception............

So, I reinstall the VS2015, use "Windows10 uap pack tool" version 1.0, and fill all kinds of, all sizes of Tile file, SplashScreen. It works!!........

This is a known issue in update 1.1

To workaround this issue, add the below ItemGroup in your project file and regenerate the package.

<ItemGroup>

  <AppxSystemBinary Include="<Assembly Mentioned in the error>" />

</ItemGroup>
