Are there any invisible characters that do not have width AND can be
manually inserted into text? I'm looking for characters that will truly
be invisible to the user, but that I can use to delimit special words
in the text.
For example, I may want to insert the word "help" and be able to locate
that particular word any time I want without confusing it with the word
"help" that the user may have entered themselves. If I could insert an
invisible character before and after that particular instance of help,
then I could distinguish it from the rest of the text.
I've tried manually inserting a NULL character (0), but the text system
doesn't seem to allow that. Anyone know of other invisible characters
that can be used in this way (or another method of programmatically
delimiting text that's invisible to the user)?
