fun Char . titlecase ( ) : String
(source)

Converts this character to title case using Unicode mapping rules of the invariant locale.

This function supports one-to-many character mapping, thus the length of the returned string can be greater than one. For example, '\uFB00'.titlecase() returns "\u0046\u0066" , where '\uFB00' is the LATIN SMALL LIGATURE FF character ( ). If this character has no title case mapping, the result of uppercase is returned instead.

import kotlin.test.*

fun main(args: Array<String>) {
//sampleStart
val chars = listOf('a', 'Dž', 'ʼn', '+', 'ß')
val titlecaseChar = chars.map { it.titlecaseChar() }
val titlecase = chars.map { it.titlecase() }
println(titlecaseChar) // [A, Dž, ʼn, +, ß]
println(titlecase) // [A, Dž, ʼN, +, Ss]
//sampleEnd

fun Char . titlecase ( locale : Locale ) : String
(source)

Converts this character to title case using Unicode mapping rules of the specified locale .

This function supports one-to-many character mapping, thus the length of the returned string can be greater than one. For example, '\uFB00'.titlecase(Locale.US) returns "\u0046\u0066" , where '\uFB00' is the LATIN SMALL LIGATURE FF character ( ). If this character has no title case mapping, the result of uppercase(locale) is returned instead.

import java.util.*
import kotlin.test.*

fun main(args: Array<String>) {
//sampleStart
val chars = listOf('a', 'Dž', 'ʼn', '+', 'ß', 'i')
val titlecase = chars.map { it.titlecase() }
val turkishLocale = Locale.forLanguageTag("tr")
val titlecaseTurkish = chars.map { it.titlecase(turkishLocale) }
println(titlecase) // [A, Dž, ʼN, +, Ss, I]
println(titlecaseTurkish) // [A, Dž, ʼN, +, Ss, İ]
//sampleEnd
