REPEAT . . . UNTIL loop problem

Replacing “ UNTIL exit == 1;” with “ UNTIL exit == 1;”, I can cause a syntax error

This might be a good practical joke for messing up other people’s code

Pasting this above into a Unicode viewer, I see a U+FEFF just before “UNTIL”. The handling of this code point (U+FEFF) is not affected by the recent change I’ve mentioned (https://www.hpmuseum.org/forum/thread-99...#pid168514 , https://www.hpmuseum.org/forum/thread-80...#pid168515).

For this (U+FEFF), I’m thinking that hidden characters should not be so (so hidden, that is). (U+FEFF’s use as a zero-width non-breaking space is deprecated [U+FEFF is also used as a byte-order mark], so having it visible seems reasonable — and preferable to its current handling.)
