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

Structure members

`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 Grapheme Cluster Boundaries 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, 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)
