¿Qué es este extraño código? [cerrado]
I have stumbled across this code:
"".length
It should obviously return 0, but for some reason returns 1337. Is this some kind of trick i dont know?

El código es:
- Cotización abierta
- Unicode Character 'ACTIVATE ARABIC FORM SHAPING' (U+206D) × 1337
- Cerrar cita
.length
Since the string is made of 1337 "invisible" characters, the length is 1337.

¿Acaso te has sordeado intencionalmente put 1337 invisible characters in there? (specifically, U+206d) - tckmn
It is ¡cero! jsfiddle.net/6CPK4 or maybe not! jsfiddle.net/6CPK4/1 - Matteo Tassinari
i would say the expected result is weird - Prabhu Murthy
@MatteoTassinari this is the JS violín with the OP's string copy/pasted into it. It shows the 1337 length. - lurker
The effect is kind of ruined when your browser fails to perform font substitution and instead renders 1337 little "unknown character" boxes XD - Niet the Dark Absol
