Hi guys,

can someone explain the following behaviour?

Why I can't decode the string?

process.env
={
VERSION: "2v00",
GIT_COMMIT: "ff35517",
BOARD: "ESP8266_4MB",
FLASH: 0, RAM: 81920,
SERIAL: "cc50e30f-0b50",
CONSOLE: "Serial1",
MODULES: "Flash,Storage,hea" ... "r,crypto,neopixel",
EXPTR: 1073643636 }

Best regards

You are using a special character > 127 and that does not look like these are supported.

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/encodeURIComponent

chars as part of RFC spec

https://tools.ietf.org/html/rfc3986

May we ask what specifically is attempted to be decoded and for what purpose? There may be other ways to skin a rabbit . . .

If you try decodeURIComponent("%E4") in your web browser it'll fail too - so Espruino is just attempting to implement it as per the spec.
