Confirmation Receipt

Gmail is usually pretty good about catching on to spam emails, but for months I've been getting spam with the subject line beginning with C𝐨𝐧𝐟𝐒𝐫𝐦𝐚𝐭𝐒𝐨𝐧 R𝐞𝐜𝐞𝐒𝐩𝐭.  This odd bolding made me look for its cause and I started by using the ASCII Text to Hex Code Converter found at the link below.  I pasted the text and clicked convert, which led to the string of characters seen at the bottom of the screenshot.  It was then obvious the 5-digit codes were the cause of the bolding. I did a Google search on the first one (1D428) and found it's part of Unicode's Mathematical Alphanumeric Symbols Block.  I eliminated this spam by creating a Gmail filter using C𝐨𝐧𝐟𝐒𝐫𝐦𝐚𝐭𝐒𝐨𝐧 R𝐞𝐜𝐞𝐒𝐩𝐭 as the subject and directly deleting them.
