WhatsApp introduced the font and writing style to improve the way we chat. You can make a word or sentence bold, italicize or strike it.
This is how to use the feature:
Bold
To bold word(s) or sentences, for example, Mazino Oyolo Kigho, add the * character before and after it in this way: *Mazino Oyolo Kigho*. This will make the names bold.
Italic
To italicize word(s) or sentences, for example, Mazino Oyolo Kigho, add the _ character before and after it in this way: _Mazino Oyolo Kigho_. This will make the names italicized.
Strike
To strike word(s) or sentences, for example, Mazino Oyolo Kigho, add the ~ character before and after it in this way: ~Mazino Oyolo Kigho~. This will strike the names.
I’m quite sure WhatsApp will introduce more writing style and fonts as time goes on. Make sure you are using the updated WhatsApp version to use this features.
