为什么不允许Visual Studio(Xamarin)中的Android资产文件带有重音符号? [英] Why are Android Asset files in Visual Studio (Xamarin) not allowed to have accents?
问题描述
我有一个Visual Studio(Xamarin，Android)项目，该文件的名称中带有重音符号:
I have a Visual Studio (Xamarin, Android) project with a file which has an accent character in the name:
diário.png
此文件位于Assets文件夹中，并标记为Android Asset.
This file is in the Assets folder, and marked as an Android Asset.
不幸的是，在构建项目时，出现编译错误:
Unfortunately when I build the project, I get a compile error:
C:\Users\vchel\Documents\FlatRedBallProjects\AndroidSpecialCharacter\AndroidSpecialCharacter\obj\Debug\assets\content\gumproject\dißrio.png : error : Invalid filename. Unable to add.
C:\Users\vchel\Documents\FlatRedBallProjects\AndroidSpecialCharacter\AndroidSpecialCharacter\obj\Debug\assets\content\gumproject\dißrio.png : error : Invalid filename. Unable to add.
请注意，该文件在我的项目中是diário.png，但错误将其引用为dißrio.png.
Notice that the file is diário.png in my project, but the error references it as dißrio.png.
如果我将文件重命名为diario.png(字母a上方无重音)，则项目构建良好.
If I rename the file to diario.png (no accent above the letter a) the project builds fine.
我知道我可以通过不使用文件中的重音符来解决此问题，但这似乎是一个奇怪的限制.这是一个已知的问题?除了避免在文件名中使用重音符号之外，还有其他解决方法吗?
I know I could work around this by not using accent characters in my file but this seems like a strange restriction. Is this a known issue? Is there another way to solve this other than avoiding using accents in file names?
推荐答案
资产命名限制一直绑定到Android API 1，相关的构建工具和.apk打包(并且与Xamarin无关)框架).
Asset naming restrictions are bound all the way back to Android API 1, the related build tools and .apk packaging (and has nothing to due with the Xamarin framework).
-
用于命名资源的有效字符为[a-z，_，0–9]
Valid characters for naming resources are [a-z, _, 0–9]
- 小写字母，数字和下划线
使用下划线(_)作为资产中单词"之间的多名称分隔符
Use an underscore (_) as a multi-name separator between "words" in your assets
- 连字符，不能使用句点
第一个字母可以是_或小写字母
The first letter can be either _ or a small case character
- 数字不能作为第一个字符
注意:Android Developer网站上曾经有关于这些限制的说明，但是由于它们剥夺了大多数用于构建工具的文档，我再也找不到它们了
Note: There used to be notes on these restrictions on the Android Developer site, but I can no longer find them as they stripped out most docs for the build tools
