I have seen serval social media channels using unicode to make part of their text bold or italicised on website such as Twitter, where this sort of thing is usually not possible. It crossed my mind that this could interfere with accessibility for screen reader users - especially since on Twitter, styled text seems to count for double the characters (e.g. 𝗛𝗲𝗹𝗹𝗼 counts as 10 characters).
Can screen readers read this sort of text as easily as regular text?
Examples: 𝗛𝗲𝗹𝗹𝗼 𝘁𝗲𝘅𝘁 𝘀𝘁𝗿𝗶𝗻𝗴 𝐻𝑒𝑙𝑙𝑜 𝑡𝑒𝑥𝑡 𝑠𝑡𝑟𝑖𝑛𝑔
