capitalize

actual fun String.~~capitalize~~(): String(source)

Deprecated

Use replaceFirstChar instead.

Replace with

import java.util.Locale

replaceFirstChar { if (it.isLowerCase()) it.titlecase(Locale.getDefault()) else it.toString() }

Returns a copy of this string having its first letter titlecased using the rules of the default locale, or the original string if it's empty or already starts with a title case letter.

The title case of a character is usually the same as its upper case with several exceptions. The particular list of characters with the special title case form depends on the underlying platform.
