StringIndexError when trying to create a StringDocument based on a UTF8 string

[alexzandros]

I'm trying to create a StringDocument based on a string that contains utf-8 characters, and all i'm getting is a StringIndexError

My code is as follows

str = "Lo que tengamos que hacer, apoyar, enteegar el ❤️ y el alma por nuestro país. Ivan es el Man. 👏👏👏#Duquepresidente https://t.co/Dr1LdTa5yQ"
sd = StringDocument(str)

And I get the following error

Error showing value of type StringDocument{String}:
ERROR: StringIndexError: invalid index [50], valid nearby indices [48]=>'❤', [51]=>'️'

Followed by a stack trace.

So, I need to know what is the best practice for working with utf strings.

Thanks in advance.

Can you paste the stack trace you saw? Looks like a bug on our side.

I also experienced the same issue. The text in question contains Less likely working with code I don’t like and the stacktrace is

ERROR: LoadError: StringIndexError: invalid index [38], valid nearby indices [36]=>'’', [39]=>'t'
