How do I write special characters like punctuation, symbols, emoji, and accented or "foreign" characters?
These characters can be written using HTML entity syntax. For example, an en-dash can be written using
– , and a Euro currency symbol can be written using
€ . W3 Schools has an HTML Punctuation reference list.
Unicode characters can be added directly. An easy option for emoji is to copy and paste from getemoji.com. Here's a smiley face. 😀
