In the past, whatsapp did not allow users to use bold, italic and other text input, but now whatsapp allows users to use bold, italic and other different styles of text. According to foreign media reports, there are two specific methods:
1.) Type directly on Whatsapp keyboard
2.) Enter by entering special symbols
Entering special symbols is like entering *I am a man* at the beginning and end of the text, and the system will turn the middle text, “I am a man” into bold. If you type in italics, you can type _I am a man_ at the beginning and end of that text. If you want to type monospace, you can type ““I am a man“` if the code has a font. But note that there must be no spaces at the beginning and input, and must be followed by text.
Using this magic weapon, users of WhatsApp API can use more and more various types, and contact customers with some important information correctly and clearly!
