Basic Usage

Inspect a Code Point

Run Sauva without arguments to open the default code point:

sauva

You can also specify a character or code point:

sauva あ
sauva U+2192

The Inspector shows the selected code point's properties and glyph preview.

• Use h / l or Left / Right to inspect adjacent code points.
• Use j / k or Down / Up to select a property, then y to copy its value.
• Press / to search, or p, r, b, or c to browse.
• Press F1 for help with the current screen.
• Press q or Esc to quit from the Inspector. Ctrl-C quits from any screen.

Analyze a String

Pass a string containing multiple code points to open Sequence mode:

sauva 'Á👩‍💻'

The list preserves the input order and groups code points into grapheme clusters.

1. Use j / k or Down / Up to select a code point.
2. Press Enter to open it in the Inspector, then Backspace to return.
3. Press n in Sequence to compare normalization forms.

Use --text when a string would otherwise be interpreted as code point notation:

sauva --text 41

Read from a Pipe or File

Use --text - to read literal UTF-8 text from a pipe or file:

printf 'Á👩‍💻' | sauva --text -
sauva --text - < input.txt

Whitespace and trailing newlines are preserved.

For all input rules and options, see Command Line Options. The complete controls are listed in Keybindings.
