See :ref:`Specification` for details of cell measurement. This implementation differs from Markus Khun's original POSIX C implementation, in that this ``wcswidth()`` processes graphemes strings yielded by :func:`wcwidth.iter_graphemes` defined by `Unicode Standard Annex #29`_. POSIX wcswidth(3) is not grapheme-aware and does not measure many kinds of Emojis or complex scripts correctly. :param pwcs: Measure width of given unicode string. :param n: When ``n`` is None (default), return the length of the entire string, otherwise only the first ``n`` characters are measured. :param unicode_version: Ignored. Retained for backwards compatibility. .. deprecated:: 0.3.0 Only the latest Unicode version is now shipped. :param ambiguous_width: Width to use for East Asian Ambiguous (A) characters. Default is ``1`` (narrow). Set to ``2`` for CJK contexts. :returns: The width, in cells, needed to display the first ``n`` characters of the unicode string ``pwcs``. Returns ``-1`` for C0 and C1 control characters! .. _`Unicode Standard Annex #29`: https://www.unicode.org/reports/tr29/ Nrc&t|dSNr"rcr's rzwcswidth..fgaQ`>a>ar!rF9.0.0rT)isascii isprintablelenrrminrrr rrr r r r )r#r$r&r'_wcwidthr total_widthrlast_measured_idxlast_measured_ucslast_measured_wprev_was_virama cluster_width vs16_nw_table vs15_wn_table _bisearchcharucs ri_beforejws ` rwcswidthrI=sH yT\\^^y(8(8(:(:y4yy,_==O)Q..ww4a4a4a4aHy#d)))c!SYY&7&7CK COOM'0M'0MI ))Cy$ii &== qq3"#"'q"'q  &==.!33y*M:: " !

See :ref:`Specification` for details of cell measurement. Unlike :func:`wcswidth`, this function applies per-terminal correction tables for emoji presentation and grapheme clusters. :param pwcs: Measure width of given unicode string. :param n: When ``n`` is None (default), return the length of the entire string, otherwise only the first ``n`` characters are measured. :param unicode_version: Ignored. Retained for backwards compatibility. :param ambiguous_width: Width to use for East Asian Ambiguous (A) characters. Default is ``1`` (narrow). Set to ``2`` for CJK contexts. :param term_program: Terminal software identifier for table correction. ``True`` (default) reads the ``TERM_PROGRAM`` or ``TERM`` environment variable for auto-detection. ``False`` disables override lookup. Accepts a canonical terminal name matching :func:`list_term_programs`, such as from XTVERSION_, ENQ_, or ``TERM_PROGRAM``. .. versionadded:: 0.8.0 :returns: The width, in cells, needed to display the first ``n`` characters of the unicode string ``pwcs``. Returns ``-1`` for C0 and C1 control characters!
