some question about "fromCharCo"

[Clayblockunova]

Currently, "fromCharCo" is defined as "from3har3o".split(3).join("C"). but I tried "from0har0o".split(0).join("C"), i's shorter and works will in Chromium. What did you think at that time?

That's because of the toString optimization which makes "from3har3o" shorter than "from0har0o" when encoded as (420302320151902).toString(31). Chromium browsers don't use that definition for "fromCharCo", they use the default encoding.
