constant regex has extra escape slash

[tirthb]

The original regex was [1-2][0-9]{3}\-[0-1][0-9]\-[0-3][0-9]

But the contant regex in the general sol had an extra escape character.
string public constant regex = "[1-2][0-9]{3}\\-[0-1][0-9]\-[0-3][0-9]";

I don't see the difference between your two examples? The string should have extra escape characters for the constant to appear properly.

Is the matching behavior broken? Or is the problem just with the constant?

I edited the comment above. Yes, the problem is only with the constant having an extra backslash. Only the first one.

You need to escape the backslash in a solidity string literal. For example:

ParserError: Expected string end-quote.

  |         const foo = "\";
