We'd like API to determine the status of an offset. This is
particularly useful because we decided to split charAt and charBefore,
and both need to be on 'good' boundaries. Note: if any of these return
false, then incrementing by one in either direction will return true.
- boolean String.isCodePointBoundary(int offset);
- boolean StringBuffer.isCodePointBoundary(int offset);
- boolean StringBuilder.isCodePointBoundary(int offset);
- static boolean Character.isCodePointBoundary(char[] buf, int start,
int limit, int offset);
- static boolean Character.isCodePointBoundary(CharSequence seq, int
start, int limit, int offset);
