Edge supports WebAssembly but not TextEncoder or TextDecoder. This change adds a comment pointing to a polyfill that could be used. The polyfill is not added by default, because we want to let the user decide if/how to include the polyfill. Fixes #27295 Change-Id: I375f58f2168665f549997b368428c398dfbbca1c Reviewed-on: https://go-review.googlesource.com/139037 Reviewed-by: Brad Fitzpatrick <bradfitz@golang.org>
