I beg to differ on your restriction. We are talking about having pure
unstyled Text that we want to Spell Check. We are NOT grammar checking but
just doing a "Is this string of characters one of those on our list of
'valid spellings of words'" operation. Thus the string "wachstube" can be
spelled with or without the "long s" glyph and still be valid. Unless the
use of the "long s" glyph is not appropriate in any word where s occurs (or
vice versa), the existence of the ZW[N]L should not come into play for
doing the string checking. If you want to treat "long s" as a different
character than "s" (ie: The string is only valid if the "long s" is/isn't
used) then-and-only-then should the existence of a ZW[N]L be used in the
Spell Checking validation process.
The text may include ZW[N]L codes to mark where we want the characters to
use/not-use ligature glyphs (when directly printed or input into a
WordProcessor). Thus "of[ZWL]f[ZWL]ice" is a totally correct way to "spell"
office if I want to get o[ffi]ce when I print this text file or import it
into InDesign/Office2k/name-your-favorite-WP.
