Invalid minus sign in DecimalFormatSymbols for "hr" locale

[mnorsic]

Please provide a brief summary of the bug

Recently I have upgraded Java from 11 to 17, and while running some unit tests, I have discovered that minus sign is not as expected (standard character '-' which is ASCII decimal value 45 or 0x2d), but some weird hex character 0x2212.

I'm running Temurin 17.0.6 both on Windows 11 and in WSL, and I see the same behavior on both versions.

Please provide steps to reproduce where possible

var locale = new java.util.Locale("hr");
var sym = java.text.DecimalFormatSymbols.getInstance(locale);
var minusSign = Integer.toHexString(sym.getMinusSign());  // equals to "2212" instead of "2d"

Expected Results

Minus sign should be mapped correctly to 2d, or ASCII 45.

Actual Results

DecimalFormatSymbols.getInstance() for "hr" locale returns non-ASCII minus sign that equals to 0x2212.
