Normalization

From Sequence, press n to compare the input with its NFC, NFD, NFKC, and NFKD normalized forms.

Forms

Canonical normalization handles equivalent representations, such as a precomposed accented letter and a letter followed by a combining mark. Compatibility normalization also converts characters such as circled digits and ligatures, and can remove distinctions in their original presentation. See Unicode Normalization Forms for the specification.

Examples of individual transformations:

Comparison

The comparison screen shows:

• The original text and its code point sequence.
• Whether each form changes the input.
• Code point (CP), UTF-8 byte (Bytes), and grapheme cluster (GC) counts for each form.
• The selected form's result, code point sequence, and number of changed regions.

Changed regions use the configured difference colors and underlining. Spaces and invisible characters are represented with display aids; the copied result contains the actual normalized text.

Inspect a Result

Select a form and press Enter to open its code point list.

The result is shown alongside the original code point list. As you select a result code point, the corresponding region in the original is highlighted and brought into view. This makes compositions and expansions easier to follow.

Press Enter again to inspect a result code point. Backspace in the Inspector returns to the result list; Backspace or Esc in the result list returns to the form comparison.

The original input is preserved throughout these operations.

Operations

Copying includes whitespace and newlines in the normalized result. Select a form and press y in the comparison screen to copy the whole result.
