How Can I Properly Encode a String with Special Characters (like 'ñ') in UTF-8 Using Java?

UTF-8 String Encoding Dilemma

You're encountering difficulties encoding a string containing the special character "ñ" into UTF-8 format. Your current approach of using myString.getBytes() followed by reconstructing a string with new String(ptext, "UTF-8") isn't producing the desired result.

Solution: Utilizing StandardCharsets

To effectively encode your string using UTF-8, consider employing the StandardCharsets interface from the Java NIO package. This class provides static references to instances of the default character set for a given language or environment.

UTF-8 Encoding Implementation

Using StandardCharsets for UTF-8 encoding involves the following:

ByteBuffer byteBuffer = StandardCharsets.UTF_8.encode(myString);

This code creates a ByteBuffer that encapsulates the UTF-8 representation of your string. The byteBuffer can then be used in various operations requiring UTF-8 encoded data.
