.. index:: remove_diacritics_codes/2
.. _text_diacritics/0::remove_diacritics_codes/2:

``remove_diacritics_codes/2``
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Canonically decomposes text, removes all Unicode Mark-category code points, and returns NFC text.

| **Compilation flags:**
|    ``static``

| **Template:**
|    ``remove_diacritics_codes(Codes,Removed)``
| **Mode and number of proofs:**
|    ``remove_diacritics_codes(+list(integer),-list(integer))`` - ``one_or_error``

| **Exceptions:**
|    An input element is not a Unicode scalar value:
|        ``domain_error(unicode_scalar_value,Code)``

.. index:: fold_diacritics_codes/3
.. _text_diacritics/0::fold_diacritics_codes/3:

``fold_diacritics_codes/3``
^^^^^^^^^^^^^^^^^^^^^^^^^^^

Removes Unicode marks, applies profile transliterations to remaining code points, and returns NFC text.

| **Compilation flags:**
|    ``static``

| **Template:**
|    ``fold_diacritics_codes(Codes,Profile,Folded)``
| **Mode and number of proofs:**
|    ``fold_diacritics_codes(+list(integer),+object_identifier,-list(integer))`` - ``one_or_error``

| **Exceptions:**
|    An input element is not a Unicode scalar value:
