caseLocale >= 0: Lowercases [srcStart..srcLimit[ but takes context [0..srcLength[ into account. caseLocale invalid input: '<' 0: Case-folds [srcStart..srcLimit[.

Throws:

IOException

internalToUpper

private static void internalToUpper(int caseLocale,
 int options,
 CharSequence src,
 Appendable dest,
 Edits edits)
                             throws IOException

Throws:

IOException

toLower

public static String toLower(int caseLocale,
 int options,
 CharSequence src)

toLower

public static <A extends Appendable> A toLower(int caseLocale,
 int options,
 CharSequence src,
 A dest,

                                                     throws IOException

Input: c is a letter I with or without acute accent. start is the index in src after c, and is less than segmentLimit. If a plain i/I is followed by a plain j/J, or an i/I with acute (precomposed or decomposed) is followed by a j/J with acute, then we output accordingly.

Returns:

the src index after the titlecased sequence, or the start index if no Dutch IJ

Throws:

IOException
