\+ connected with ^ and alternative

[madameczek]

Hi, just tried:
Patterrn: @"^(\+|\d)" this should match '+' or '0' (from input1: @"+" or imput2="0"), but it doesn't. Only '0' is asserted as matching.
When remove ^ and pattern is (+|\d), then it matches both '+' and '0'

^(\+|\d) works perfectly with 0123 and +5454 for me. Got any specific example?
