There was a problem hiding this comment.
Should we add a similar up-call for the bytes --> String direction so that we support decoding as well?

* [Proposal] Add "String Encoding Names" proposal. This proposal allows `String.Encoding` to be converted to and from various names. For example: ```swift print(String.Encoding.utf8.ianaName!) // Prints "UTF-8" print(String.Encoding(ianaName: "ISO_646.irv:1991") == .ascii) // Prints "true" ``` * Change the link to implementation. * Remove description about #1015 since it is resolved. Links: - Issue: #1015 - Resolvers: * #1217 * swiftlang/swift-corelibs-foundation#5194 * Add a description about already-available ICU string converter.
