The speaker icon unicode 1f50a is 5 digits from the "Miscellaneous Symbols and Pictographs" family and when I try and display it I get " a" so apparently I am getting 1f50 (which doesn't exist so blank) followed by "a". I can display any 4 digit unicode character but can't find how to display the longer ones. I know the tablet can display it as I can see it in the Unicode Map app.
textSound = (TextView)findViewById(R.id.textSound);
textSound.setText("\u1f50a");

To insert a Unicode character, type the character code, press ALT, and then press X. For example, to type a dollar symbol ($), type 0024, press ALT, and then press X. For more Unicode character codes, see Unicode character code charts by script.
Unicode supports more than a million code points, which are written with a "U" followed by a plus sign and the number in hex; for example, the word "Hello" is written U+0048 U+0065 U+006C U+006C U+006F (see hex chart).
Unicode input is the insertion of a specific Unicode character on a computer by a user; it is a common way to input characters not directly supported by a physical keyboard. Unicode characters can be produced either by selecting them from a display or by typing a certain sequence of keys on a physical keyboard.
Suppose a method getUnicode(char c) . A call getUnicode('÷') should return \u00f7 . Characters are already unicode in Java.
These characters cannot be represented directly in a Java string since it uses only 16 bits per character. But there is an escaping mechanism called "surrogate pairs". The character number 1f50a for example can be represented by the two 16 bit 'characters' D83D and DD0A. So something like "\uD83D\uDD0A" might work (I did not try it). It still depends if this character is available in the used font.
