+/**
+ * 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.
