These values can be bitwise ORed together (e.g., SPLIT_FIXED | SPLIT_CONTINUATION) to provide fallback split methods. In the example given, an attempt will be made to split the word using the rules of SPLIT_CONTINUATION; if there is not enough room, the word will be split with the rules of SPLIT_FIXED. These combinations are also available as the following values:

• SPLIT_CONTINUATION_FIXED
• SPLIT_HYPHENATION_FIXED
• SPLIT_HYPHENATION_CONTINUATION
• SPLIT_ALL
