!!! tip
To end a hashtag, you can simply use a space, for example in the text `this #soup rules`, the hashtag is terminated by a space so `#soup` becomes the hashtag. However, you can also use a pipe character `|`, or the unicode characters `\u200B` (zero-width no-break space) or `\uFEFF` (zero-width space), to create "partial-word" hashtags.

Likewise, with the input text `this #so​up rules`, which contains an invisible zero-width space after the o and before the u, only the `#so` part becomes the hashtag.
