WhatsApp for iOS, Android: How to add bold, italics and strikethrough formatting options
Soon after WhatsApp announced that it introduced text formatting tools for Android beta, the features are now available for users running version 2.12.17 on iOS and version 2.12.535 for Android.
A report by Telegraph explains that once WhatsApp is updated, you add asterisks to either side of your text, e.g. *hello* to format your text into bold. To italicise, add underscores either side, e.g. _hello_ and to strike through text, add tildes either side, e.g. ~tilde~. One can also combine the new formats, such as _*bolditalics*_. For now this is not a feature per se but more like a temporary workaround. Moreover, it works cross platform, only if your friend has the above mentioned versions of WhatsApp installed on their smartphones.
