Answer 1

If you have only bell characters, you can use:

String data="164/165/165"; //the hidden bells are there, generated via echo $'164\a/165\a/165' | pbcopy
System.out.println("length with hidden bells: "+data.length());

String elems [] = data.split("\\a/");
for(String e:elems) {
    System.out.println(e);
    System.out.println(e.length());
}

output:

length with hidden bells: 13
164
3
165
3
165
3

You can also use the hexadecimal notation: \\x07

Notes:

If you have different special characters you can create a char class via the hexadecimal values or you can simply use \\D+ if you are only interested in extracting digits from the string or \\\\W+ if your string also contains letters. Also if your / is always preceded by a character you want to discard, then ./ should work fine too.
