Another use case, archaic as it may seem, is still important: processing
fixed-length fields in text files.

Such applications are probably not using Unicode ...
In Unicode-land, the concept is pretty meaningless: are you
talking about
(1) a fixed display width (number of columns) - if so the
numbers of "characters" (or bytes") is unrelated to the display
width; or
(2) a fixed number of bytes in a file - if so immediately fire anybody who writes any new applications doing this! (And "legacy" applications
will not support Unicode.)
