'StringBuilder.append(CharArray, offset, len)' call on the JVM

Reports a StringBuilder.append(CharArray, offset, len) function call on the JVM platform that should be replaced with a StringBuilder.appendRange(CharArray, startIndex, endIndex) function call.

The append function behaves differently on the JVM, JS and Native platforms, so using the appendRange function is recommended.

Example:

fun f(charArray: CharArray, offset: Int, len: Int): String {
    return buildString {
        append(charArray, offset, len)
    }
}

After the quick-fix is applied:

fun f(charArray: CharArray, offset: Int, len: Int): String {
    return buildString {
        appendRange(charArray, offset, offset + len)
    }
}
