Oops, noticed the blooper in my post that led to the misunderstanding.
Fixed it.

I was under the impression ⁠ was just another way of saying Word Joiner though I haven't seen many differences between using ZWJ and WJ. Continuing with the joiners, a quick check says I've used the ZWNJ 4 times in the last 11 years to suppress ligatures.

⁠ is the entity for "word joiner" (U+2060). It used to be that the dual-use code point for "zero width non-breaking space" and "Unicode byte order mark" (U+FEFF) was treated like "word joiner", but that use is deprecated since the new code point has been defined.

The difference between ‍ and ⁠ is that despite the definition, ⁠ means "avoid breaks unless there is absolutely no alternative", while ‍ means "the two characters on either side cannot be separated under any circumstances, because it would change the meaning of the text".

Likewise, using ‌ is not truly correct for avoiding stylistic ligatures, but should be used to avoid ligatures that change the meaning of the text.

Three of the times I used it was helping an co-worker with an old German text.
