File browser sort order inconsistent

On initial load of a browse page the files and directories are sorted server-side, on subsequent navigation the files and directories are sorted client-side. There are some inconsistencies with this sort order for non-alphanumeric characters.

To reproduce:

• Browse source for a repo with folders that start with non-alphanumeric characters - for example "AAA" and "{AAA}"
• click through to a folder
• use "Back" in your browser

Expected results:

• Files/Folders are in the same order

Actual results:

• "{AAA}" comes first when sorted client-side, "AAA" comes first when sorted server side
