voidwriteUTF8(DataOutput buf, String value)
Writes an UTF8 string to a byte buffer. 
final byte[] bytes = value.getBytes(StandardCharsets.UTF_8);
if (bytes.length >= Short.MAX_VALUE) {
    throw new IOException(
            "Attempt to write a string with a length greater than Short.MAX_VALUE to ByteBuf!");
writeVarInt(buf, bytes.length);
buf.write(bytes);
voidwriteUTF8(final String filePath, final String content)
write UTF 
Files.write(FileSystems.getDefault().getPath(filePath), content.getBytes(StandardCharsets.UTF_8));
voidwriteUTF8(OutputStream out, String str)
Writes the string out as UTF-8 
byte[] s = str.getBytes(UTF8);
out.write(s);
voidwriteUtf8String(final DataOutputStream out, final String str)
Writes a UTF-8 string to the buffer. 
byte[] bytes = str.getBytes(CHARSET_UTF8);
if (bytes.length > MAXLEN) {
    throw new IllegalArgumentException("Encoded UTF-8 string too long.");
out.writeShort(bytes.length);
out.write(bytes);
voidwriteUTF8WithLength(OutputStream out, String str)
Writes out a 4 byte integer of the length (in bytes!) of the String, followed by the String (as UTF-8) 
byte[] s = str.getBytes(UTF8);
writeInt4(out, s.length);
out.write(s);
