What steps will reproduce the bug?
All you need is to run
assert.deepEqual("👨👩👧👦", "");inside a test case.
How often does it reproduce? Is there a required condition?
Seems to happen every time there's a ZWJ in the test.
What is the expected behavior? Why is that the expected behavior?
It should not crash the parser, because it doesn't make sense for it to crash the parser. ZWJ should log correctly.
What do you see instead?
Well, it crashes the parser:
Error [ERR_TAP_LEXER_ERROR]: Unexpected character: at line 1, column 0
at Socket.emit (node:events:511:28) {
code: 'ERR_TAP_LEXER_ERROR'
}
