<p>(See the Unicode Standard, chapter 3, Default Case Conversion, R3 toTitlecase(X).) Option bit for titlecasing APIs that take an options bit set.</p>
<p>This used to be the default index adjustment in ICU. Since ICU 60, the default index adjustment is to the next character that is a letter, number, symbol, or private use code point. (Uncased modifier letters are skipped.) The difference in behavior is small for word titlecasing, but the new adjustment is much better for whole-string and sentence titlecasing: It yields "49ers" and "«丰(abc)»" instead of "49Ers" and "«丰(Abc)»".</p>
<p>It is an error to specify multiple titlecasing adjustment options together.</p>
