issue description

when I used rootBundle.loadString to load a Chinese markdown file, it throwed this error

and in flutter dev 1.14.6, it works fine in debug mode(release mode still has the issue)

I'm using flutter dev v1.15.1, this issue is still exsits.

This is my web application created by flutter web: My Blog

now I use another method to parse markdown files, but this is not elegant enough。

And this issue is familiar to #46163; not only the web has this problem, but also the mobile
