RFR (XS) 8232734 [TESTBUG] avoid using JDK symbols in ExtraSymbols.symbols.txt

[Ioi Lam]

Hi Calvin,

Thanks for the review.

I'll add two more test cases:

             appendSymbol(fw, ""); // empty string
             appendSymbol(fw, "Hello_\uffff");


The generated config file looks like this:

5 -1: Hello
0 -1:
7 -1: Hello_\x01
8 -1: Hello_\xc3\xbf
9 -1: Hello_\xe1\x88\xb4
9 -1: Hello_\xef\xbf\xbf
10 -1: NewSymbol0
10 -1: NewSymbol1
10 -1: NewSymbol2
.....


Thanks
- Ioi
