Unicode characters

The standard way to identify Unicode in documentation is in the form U+code, for example: U+2192 for Rightward Arrow. The U+ prefix means that the code is a Unicode code point.

Different notations are used for inserting Unicode into different types of documents:

• inserting Unicode as a string literal into code (Python, JavaScript, etc): \u<code>, for example: \u2192

• HTML: &#x<code>, for example: →

• CSS: content: "\code", for example content: "2192"

For HTML, also see notes / Typing HTML entities in markdown documents
