Assets Named with "~" or placed in Folders with "~" cannot be used

Using an asset with a "_{" character located in its name, will not allow that asset to be assigned to any other asset's input. For example a Texture with a "}" in its name cannot be assigned to a Material's Texture Sampler or a Material with a "~" in its name cannot be assigned to a Blueprint UMG Widget Image.

This Behavior holds true if named without a "_{" but placed in a folder with a"}" in the name.

Also Reproduced in Main Promotable-CL-2493094

1. Open QAGame Editor
2. Import the attached "~Test_Texture.tga" file
3. Create a New Material
4. In the New Material, Add a Texture Sampler node
5. Attempt to assign the "~Test_Texture.tga" file

RESULTS: Texture Sampler remains unassigned

EXPECTED: Texture File is assigned to Texture Sampler Node

Alternate Repro Steps:

1. Open QAGame Editor
2. Create a New Folder Named "Test~Folder"
3. In this new Folder, Create a New Material named "M_Test"
4. Back in the Root Game Folder, Create a New UMG Widget Blueprint
5. In the New UMG BP, Create an Image
6. Attempt to Assign the M_Test Material to the Image.

RESULTS: Image in UMG BP remains unassigned

EXPECTED: M_Test is assigned to Image in UMG BP
