Considering bug #65693, I suggest that it may be worth treating an input
U+00A0 as ambiguous: is it a fixed-width non-breakable space, or a
variable-width non-breakable space? Unicode does not distinguish.
This is analogous to how we don't know whether a man page author means a
hyphen or a minus sign when they type `-`.
In my opinion preconv should either:
1. Fail and force the user to edit the input to make a real choice,
eliminating U+00A0 in the input.
2. Add an option instructing preconv which escape sequence to transform
U+00A0 into.
