unormalize

Converts UTF-8 input to the desired UTF-8 in Unicode normalization form.

Read about the Unicode Normalization Forms!

Usage

There are five executables included, that all have the exact same usage and arguments:

• unormalize
• nfc
• nfd
• nfkc
• nfkd

You may either redirect or pipe input into unormalize (and its buddies), or provide filenames as arguments.

Options

-f FORM/--form=FORM

Selects the normalization form: one of NFC, NFD, NFKC, or NFKD. The equivalently named executables imply their respective normalization form; unormalize is equivilent to nfk without the --form arugment.

-i EXTENSION/--in-place EXTENSION

Filenames must be specified as arguments. If so, this opens them, and converts them into the desired normalization form, in place. EXTENSION is the extension given to back-ups of the original files.

Examples

Convert clipboard contents to NFC (macOS):

$ pbpaste | nfc | pbcopy

Convert a file, in-place, to NFKD:

$ nfkd --in-place=.bak file.txt && rm file.txt.bak

Convert circled, variants, and half-widths to their compatible forms:

$ echo 'ℍ①ｶ' | nfkc
H1カ
