How is text based data represented in Unicode?
Unicode uses two encoding forms: 8-bit and 16-bit, based on the data type of the data that is being that is being encoded.
The default encoding form is 16-bit, where each character is 16 bits (2 bytes) wide.
Sixteen-bit encoding form is usually shown as U+hhhh, where hhhh is the hexadecimal code point of the character..
What form of data is represented by text?
Character data is commonly referred to as “text.” Digital devices employ several types of codes to represent character data, including ASCII, Unicode, and their variants.

- Images are represented in digital format in a wide variety of ways.
At the most basic level, there are two different ways of encoding the contents of a 2-D image in digital format: raster (also known as bitmap) and vector. - Textual data is information that is stored and written in a text format.
It can be anything from emails to blog posts to social media posts and online forum comments.
In short, it's any data that has been expressed in words.
