Tilde expansion is done by the shell before executing commands (including
commands to set a variable).
Programs were not supposed to be aware of it at all. They are supposed to
get expanded paths that can be directly used in system calls.
With time, users grew used to the convenience, and expected ~ to work in
other contexts, e.g. GUI, config files and envvars.
So nowdays many programs will perform the expansion themselves. But it's
not generally guaranteed to work.
Some esoteric shell constructs also might end up doing the expansion again.
Ken, if you can show us the exact commands that you used (bash and/or fish),
we'll try to help more concretely.
