The `PangoLogAttr` structure stores information about the attributes of a single character.

###### Structure members

`is_line_break:` `guint`

  If set, can break line in front of character.

`is_mandatory_break:` `guint`

  If set, must break line in front of character.

`is_char_break:` `guint`

  If set, can break here when doing character wrapping.

`is_white:` `guint`

  Is whitespace character.

`is_cursor_position:` `guint`

  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 Grapheme Cluster Boundaries semantics.

`is_word_start:` `guint`

  Is first character in a word.

`is_word_end:` `guint`

  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:` `guint`

  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:` `guint`

  Is first character in a sentence.

`is_sentence_end:` `guint`

  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:` `guint`

  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:` `guint`

  Is a whitespace character that can possibly be expanded for justification purposes. (Since: 1.18).

`is_word_boundary:` `guint`

  Is a word boundary, as defined by UAX#29. 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 Word Boundaries semantics. (Since: 1.22).

`break_inserts_hyphen:` `guint`

  When breaking lines before this char, insert a hyphen. Since: 1.50.

`break_removes_preceding:` `guint`

  When breaking lines before this char, remove the preceding char. Since 1.50.

`reserved:` `guint`
