NPE on specific regex

[ludovicianul]

Describe the bug
I get a NPE with the following regex ^[^\p{C}\p{Z}\s]*[^\p{C}]+[^\p{C}\p{Z}]*$ which didn't happen on version 1.4.

To Reproduce
Steps to reproduce the behavior:

1. regex: ^[^\p{C}\p{Z}\s]*[^\p{C}]+[^\p{C}\p{Z}]*$
2. RgxGen.parse("^[^\\p{C}\\p{Z}\\s]*[^\\p{C}]+[^\\p{C}\\p{Z}]*$").generate()
3. See error below

	at com.github.curiousoddman.rgxgen.RgxGen.parse(RgxGen.java:48)

Expected behavior
Property generate a value.

Environment (please complete the following information):

• MacOS
• JDK 21
• RgxGen Version 2.0

Additional context
It works with RgxGen 1.4.

I will look into that. Though I am curious which results did you get in 1.4, because character classes were not supported in 1.4 at all. So the results could not have been correct anyway.

[curious-odd-man]

Ok. I see that this category (\p{C}) is not yet supported :

I will try to add it.

With 1.4 I get something like the below which passes the matches test:

System.out.println("%u@O2L1K\"jn:;3e&(e<QN5q4HeN'A:(\\c^F.03-vyvKW5zW/u~h,(aSyGHPKIA);XNY#v@[hEh(Og=NEVq;0+VN#sv\\wOVE<t[RNo(Tg'nFk)\\GZ]o%|~d3KNi?J\"l2bGO#7E*BQo 8qS25\\A<8yLO<JmmP)ABDr^#kZ[$8B^R=hFMBec,;IdXF!Q[vVe|O_5]1#-$d(N#+2Vh'HbB[#M8]T6,P6VJ3sT|NGOe=5k'OO*Asrds%*@XAy".matches("^[^\\p{C}\\p{Z}\\s]*[^\\p{C}]+[^\\p{C}\\p{Z}]*$"));
