  • \$\begingroup\$ @StefanReich You're right, but the same applies to almost any other existing answer, though. But I've added a note to mention this in the answer (and golfed it by 3 bytes at the same time). \$\endgroup\$ Commented Jan 26, 2021 at 19:44
  • \$\begingroup\$ Come on... you're saying there is a bug in THIS? >> à øV << (the Japt program, whatever that is) \$\endgroup\$ Commented Jan 26, 2021 at 21:53
  • \$\begingroup\$ @StefanReich The golfing languages like Jelly, Japt, 05AB1E, etc. are probably fine, since most of them just use the powerset and check if the second input is in it. I was referring to the answers using regex like mine, like the accepted Perl answer; the Python answer of Eric; the Ruby answer; etc. All answers that use regex are similar as mine (add a ".*" after each characters, and check if it matches the second input) are most likely invalid if the inputs contain special regex characters. \$\endgroup\$ Commented Jan 26, 2021 at 22:07
