Other cases include the use of certain formatting tools or text editors, which can introduce hidden characters for formatting purposes.

There has been a lot of speculation about invisible characters in AI-generated text acting as a watermark, but there is no strong evidence to support this.

However, according to some claims, this was actually an unintended bug caused by reinforcement learning, not a purposeful watermarking feature.

Invisible characters, such as formatting characters, have their purpose in certain contexts. However, if you have copied text from a source that included these invisible characters, it is likely that you do not need them in your text. Furthermore, unintended invisible characters can make it more difficult to search or process your text, because text that contains invisible characters may look identical to text without them, but have a different length. In programming, this can cause comparisons to fail, as the two pieces of text are not considered the same.
