String parameters send with text protocol use a lot of array to be send to server.
actual :

• String.getByte("UTF-8") = String transformation to UTF-8 (= creation of an array with size 3*string length, transform char array to this byte. Copy to an array of the definitive size,
• loop every byte to escape ' char or ',\," caracters according to escape mode.
• send to ouput

decoding string to UTF-8 to a an array with size 3*string length (escape chars are ASCII, so escape char are 1 byte) with direct escape. When definitive size is known, write directly to output
