Feedback
We are using the ktor client in a multiplatform project (android, iOS and web). Starting with version 1.1.0 the build of the JS client fails with the following message:

ERROR in ./kotlinx-io.js
Module not found: Error: Can't resolve 'text-encoding' in '<mypath>\kotlinmultiplatform\web\build\kotlin-js-min\main'
@ ./kotlinx-io.js 5309:21-45 5320:21-45
@ ./ktor-utils.js
@ ./web.js

If I manually add text-encoding as a npm-dependeny, it works.

If I list the npm dependency tree with the previous working ktor version 1.0.1 I get:

+-- kotlinx-io@0.1.4 -> <mypath>\kotlinmultiplatform\web\build\node_modules_imported\kotlinx-io extraneous
+-- kotlinx-io-js@0.1.1 -> <mypath>\kotlinmultiplatform\web\build\node_modules_imported\kotlinx-io-js
| +-- kotlin@1.3.10
| +-- kotlin-test@1.3.10
| | `-- kotlin@1.3.10 deduped
| +-- kotlinx-atomicfu@0.11.12 -> <mypath>\kotlinmultiplatform\web\build\node_modules_imported\kotlinx-atomicfu deduped
| `-- text-encoding@0.7.0

If I list the npm dependency tree with a ktor version >= 1.1.0 the kotlinx-io-js (and of course text-encoding) is missing
