Symbols include space ( ), coma (,), full stop (.), semicolon (;) and most likely any other characters, that are allowed in name string but require escaping when getting the path.

To reproduce:
1. Open any project, that has one of the symbols above in it's name, switch to Android platform (or use default name as it contains spaces - "New Unity Project (x)")
2. In Player Settings > Publishing Settings, create a new Keystone (Anywhere) and use it
3. Try building the application

Expected: application is built
Actual: errors are thrown, preventing application from being built

Reproduced in: 2019.2.0a1, 2019.2.0a10
Not reproduced in: 2017.4.25f1, 20118.3.12f1, 2019.1.0b10

Note: errors differ across the 2019.2 releases, most of them indicating that keystore cannot be found in the location provided.

Errors include:
"stderr[
Unexpected parameter(s) after input APK (Proj/yep.keystore)
]"

"UnityException: Can not sign the application
Unable to sign the application; keystore file not found!
UnityEngine.GUIUtility:ProcessEvent(Int32, IntPtr)
"
