# Formats
This site discusses three formats.
- [Unicode](Unicode.md)
- Any sequence of [Unicode Scalar Values], encoded with a standard
[Unicode encoding form].
- [Basic Text](BasicText.md)
- This is intended to realize the intuitive phrases "text" or "plain text"
which are used in many contexts. It excludes control characters and other
content unnecessary or impractical for text.
- [Restricted Text](RestrictedText.md)
- Restricted Text is a hypothetical format at this time.
- Like Basic Text, but aims to reduce visual ambiguity by trading off some
support for historical scripts, multiple-script text, formatting, and
symbols.
