Sentence Break - CR

CR is a specific value that marks a carriage return character, indicating a hard line break in text. In sentence boundary detection, CR typically acts as a mandatory break, meaning any sentence segmentation must end at a CR unless it is immediately followed by a character that continues the same line, such as a line feed (LF), in which case the pair is treated as a single boundary unit. This ensures that sentences do not incorrectly split across a normal line-ending sequence, while still respecting the explicit break imposed by the carriage return alone when it appears isolated.
