I think I have solved this problem. My work computer has Windows language options enabled by default that appear to conflict with emacs. I disabled the “Auto-Adjust”
option on the language toolbar, and I removed an “Alt-Shift” hotkey for switching the keyboard language, and the problems with funny characters in emacs have gone away.

Subject: 25.2; erratic keyboard mapping
When I start emacs, my keyboard mapping is fine. But after some time, the keyboard mapping spontaneously changes. For example:
-instead of backslash, < appears
-when I type left curly brace, right curly brace or apostrophe, nothing appears
-when I type left curly brace twice, ^^ appears
-when I type right curly brace twice, `` appears
Switching out of Latex mode has no effect. No other windows applications are affected. For example, my keyboard mapping in Notepad works fine. When I restart emacs, the keyboard mapping returns to normal.
I have not been able to pinpoint a precise sequence of events or amount of time leading up to the change of keyboard mapping.
