The command performs one of several Unicode character transformations, depending on *function* which may take the values described below.

[**unicode tonfc** ?**-profile** *profile*? *string*](#unicode)

Returns *string* normalized as per Unicode **Normalization Form C** (NFC).

[**unicode tonfd** ?**-profile** *profile*? *string*](#unicode~2)

Returns *string* normalized as per Unicode **Normalization Form D** (NFD).

[**unicode tonfkc** ?**-profile** *profile*? *string*](#unicode~3)

Returns *string* normalized as per Unicode **Normalization Form KC** (NFKC).

[**unicode tonfkd** ?**-profile** *profile*? *string*](#unicode~4)

Returns *string* normalized as per Unicode **Normalization Form KD** (NFKD).

The normalization forms NFC, NFD, NFKC and NFKD referenced above are defined in **Section 3.11** of the Unicode standard (see https://www.unicode.org/versions/Unicode16.0.0/core-spec/chapter-3/).

The **-profile** option determines the command behavior in the presence of conversion errors. The passed profile must be **strict** or **replace**. See the **PROFILES** section in the documentation of the **encoding** command for details on profiles.
