Liblinebreak is an implementation of the line breaking algorithm as described in Unicode Standard Annex 14. It breaks lines that contain Unicode characters. It is designed to be used in a generic text renderer. FBReader is one real-world example.
This release is a transitional release for a 2.0 release that will reduce the namespace pollution by prefixing `lb_' to symbols that users generally do not use directly. Existing users should not be impacted generally. However, new users are expected to use is_line_breakable instead of is_breakable, and remember that get_next_char_utf* will be renamed.
