Interoperability between terminal-line applications and (teletype-style) character terminals using the UTF-8 encoding requires agreement on which character should advance the cursor by how many cell positions. No established formal standards exist at present on which Unicode character shall occupy how many cell positions on character terminals. These routines are a first attempt of defining such behavior based on simple rules applied to data provided by the Unicode Consortium. For some graphical characters, the Unicode standard explicitly defines a character-cell width via the definition of the East Asian FullWidth (F), Wide (W), Half-width (H), and Narrow (Na) classes. In all these cases, there is no ambiguity about which width a terminal shall use. For characters in the East Asian Ambiguous (A) class, the width choice depends purely on a preference of backward compatibility with either historic CJK or Western practice. Choosing single-width for these characters is easy to justify as the appropriate long-term solution, as the CJK practice of displaying these characters as double-width comes from historic implementation simplicity (8-bit encoded characters were displayed single-width and 16-bit ones double-width, even for Greek, Cyrillic, etc.) and not any typographic considerations. Much less clear is the choice of width for the Not East Asian (Neutral) class. Existing practice does not dictate a width for any of these characters. It would nevertheless make sense typographically to allocate two character cells to characters such as for instance EM SPACE or VOLUME INTEGRAL, which cannot be represented adequately with a single-width glyph. The following routines at present merely assign a single-cell width to all neutral characters, in the interest of simplicity. This is not entirely satisfactory and should be reconsidered before establishing a formal standard in this area. At the moment, the decision which Not East Asian (Neutral) characters should be represented by double-width glyphs cannot yet be answered by applying a simple rule from the Unicode database content. Setting up a proper standard for the behavior of UTF-8 character terminals will require a careful analysis not only of each Unicode character, but also of each presentation form, something the author of these routines has avoided to do so far. http://www.unicode.org/unicode/reports/tr11/ Latest version: http://www.cl.cam.ac.uk/~mgk25/ucs/wcwidth.c � )�divisionN� )�WIDE_EASTASIAN)� ZERO_WIDTH)� list_versions)� lru_cache� )r iO i i i i i i( i) i* i+ i, i- i. i` ia ib ic c � � d}t |� � dz }| |d d k s| || d k rdS ||k r@||z dz }| || d k r|dz }n| || d k r|dz }ndS ||k �@dS )aJ Auxiliary function for binary search in interval table. :arg int ucs: Ordinal value of unicode character. :arg list table: List of starting and ending ranges of ordinal values, in form of ``[(start, end), ...]``. :rtype: int :returns: 1 if ordinal value ucs is found within lookup table, else 0. r r � )�len)�ucs�table�lbound�ubound�mids �F/opt/cloudlinux/venv/lib64/python3.11/site-packages/wcwidth/wcwidth.py� _bisearchr r s� � � �F� ��Z�Z�!�^�F� �U�1�X�a�[���C�%��-��"2� 2� 2��q� �F� � ����1�$�� ��s��A� � � ��1�W�F�F� �5��:�a�=� � ��1�W�F�F��1� �F� � � �1� i� )�maxsize�autoc � � t | � � }|t v rdS |dk sd|cxk rdk rn ndS t |� � }t |t | � � rdS dt |t | � � z S )a� Given one Unicode character, return its printable length on a terminal. :param str wc: A single Unicode character. :param str unicode_version: A Unicode version number, such as ``'6.0.0'``, the list of available version levels may be listed by pairing function :func:`list_versions`.

Otherwise, the number of column positions the character occupies on a graphic terminal (1 or 2) is returned. :rtype: int The following have a column width of -1: - C0 control characters (U+001 through U+01F). - C1 control characters and DEL (U+07F through U+0A0).
