/* Logical attributes of a character.

/**
 * PangoLogAttr:
 * @is_line_break: if set, can break line in front of character
 * @is_mandatory_break: if set, must break line in front of character
 * @is_char_break: if set, can break here when doing character wrapping
 * @is_white: is whitespace character
 * @is_cursor_position: if set, cursor can appear in front of character.
 * i.e. this is a grapheme boundary, or the first character
 * in the text.
 * This flag implements Unicode's
 * <ulink url="http://www.unicode.org/reports/tr29/">Grapheme
 * Cluster Boundaries</ulink> semantics.
 * @is_word_start: is first character in a word
 * @is_word_end: is first non-word char after a word
 * Note that in degenerate cases, you could have both @is_word_start
 * and @is_word_end set for some character.
 * @is_sentence_boundary: is a sentence boundary.
 * There are two ways to divide sentences. The first assigns all
 * inter-sentence whitespace/control/format chars to some sentence,
 * so all chars are in some sentence; @is_sentence_boundary denotes
 * the boundaries there. The second way doesn't assign
 * between-sentence spaces, etc. to any sentence, so
 * @is_sentence_start/@is_sentence_end mark the boundaries of those sentences.
 * @is_sentence_start: is first character in a sentence
 * @is_sentence_end: is first char after a sentence.
 * Note that in degenerate cases, you could have both @is_sentence_start
 * and @is_sentence_end set for some character. (e.g. no space after a
 * period, so the next sentence starts right away)
 * @backspace_deletes_character: if set, backspace deletes one character
 * rather than the entire grapheme cluster. This
 * field is only meaningful on grapheme
 * boundaries (where @is_cursor_position is
 * set).  In some languages, the full grapheme
 * (e.g.  letter + diacritics) is considered a
 * unit, while in others, each decomposed
 * character in the grapheme is a unit. In the
 * default implementation of pango_break(), this
 * bit is set on all grapheme boundaries except
 * those following Latin, Cyrillic or Greek base characters.
 * @is_expandable_space: is a whitespace character that can possibly be
 * expanded for justification purposes. (Since: 1.18)
 * @is_word_boundary: is a word boundary.
 * More specifically, means that this is not a position in the middle
 * of a word.  For example, both sides of a punctuation mark are
 * considered word boundaries.  This flag is particularly useful when
 * selecting text word-by-word.
 * This flag implements Unicode's
 * <ulink url="http://www.unicode.org/reports/tr29/">Word
 * Boundaries</ulink> semantics. (Since: 1.22)
 *
 * The #PangoLogAttr structure stores information
 * about the attributes of a single character.
