readUtf8

common

Removes all bytes from this, decodes them as UTF-8, and returns the string. Returns the empty string if this source is empty.

Buffer buffer = new Buffer()
    .writeUtf8("Uh uh uh!")
    .writeByte(' ')
    .writeUtf8("You didn't say the magic word!");

assertEquals("Uh uh uh! You didn't say the magic word!", buffer.readUtf8());
assertEquals(0, buffer.size());

assertEquals("", buffer.readUtf8());
assertEquals(0, buffer.size());
