Some letters are not printable - they might by like a newline or a beep code. You can see what these characters are with what is called a hexdump. This is where the value of each character is displayed in hexadecimal along side its text representation. This is extremely useful for debugging. Here’s an example from the tracing sandbox:

See the characters after dog? The value is 0x0A in hexadecimal which means the \n or newline character.
To get a hex dump with tracing it’s a matter of using BAS_HEX(Label, Data, Size) in your code. For example:
void APPrepeatSentence(const BASstring& Sentence){
BAS_FUNCTION(APPrepeatSentence);
BAS_VAR(Sentence);
BASstring Result;
BAS_TRC("About to print hello world...");
for (int i=0; i < 4; i++){
BAS_VAR(i);
Result = Result + Sentence + "\n";
}
BAS_HEX("Result", Result.data(), Result.size());
BASout << Result;
}
