String to []rune conversion about tinygo

[aykevl]

Not yet fixed, but I've improved the error message to also include the source location (see da0a02d):

$ tinygo build -o wasm.wasm -target=wasm examples/wasm
/home/ayke/src/github.com/aykevl/tinygo/src/examples/wasm/wasm.go:26:12: todo: convert from string: rune

Hey, I would like to take a stab at this.

[aykevl]

That would be great!

The feature will be very similar to the current stringFromBytes implementation converting a string to a []byte slice. The difference with converting to a []rune slice is that that needs UTF-8 decoding, but all the decoding stuff has already been implemented in the runtime so you can take a look at what's already there.
These are the places that need some additions:

tinygo/src/runtime/string.go

Line 91 in da85710

tinygo/compiler/compiler.go

Line 2387 in da85710

default:

Just ask if you have any questions.

Thanks @aykevl, Let me give it a try.

Fixed by #406.
