    String Encoding Names


Proposal: Not assigned yet 
Author(s): YOCKOW
Review Manager: TBD

Implementation:  Coming Soon


Review: (Pitch)

Introduction

This proposal lets String.Encoding be converted to/from names.
For example:
print(String.Encoding.utf8.name!) // Prints "UTF-8"
print(String.Encoding(name: "ISO-10646-UCS-4")! == .utf32) // Prints "true"
Motivation

The names for string encodings are commonly used certainly in computer networking and in other areas.
You will often find them, for instance, in HTTP headers such as Content-Type: text/plain; charset=UTF-8 ("UTF-8" is the one). You will also find them in XML documents such as <?xml version="1.0" encoding="Shift_JIS" ?> ("Shift_JIS" is the one).
As a natural consequence, it is necessary to parse and to generate such names, for example, when you generate/receive HTTP response.
Current solution

Swift is missing such APIs, therefore we have to use functions defined in CoreFoundation (hereinafter called "CF") described as below.
extension String.Encoding {
  var nameInLegacyWay: String? {
    // 1. Convert `String.Encoding` value to the `CFStringEncoding` value.
    //    NOTE: The raw value of `String.Encoding` is the same with the value of `NSStringEncoding`,
    //          while it is not equal to the value of `CFStringEncoding`.
    let cfStrEncValue: CFStringEncoding = CFStringConvertNSStringEncodingToEncoding(self.rawValue)

    // 2. Convert it to the name where its type is `CFString?`
    let cfStrEncName: CFString? = CFStringConvertEncodingToIANACharSetName(cfStrEncValue)

    // 3. Convert `CFString` to Swift's `String`.
    //    NOTE: Unfortunately they can not be implicitly casted on Linux.
    let charsetName: String? = cfStrEncName.flatMap {
      let bufferSize = CFStringGetMaximumSizeForEncoding(
        CFStringGetLength($0),
        kCFStringEncodingASCII
      ) + 1
      let buffer = UnsafeMutablePointer<CChar>.allocate(capacity: bufferSize)
      defer {
        buffer.deallocate()
      }
      guard CFStringGetCString($0, buffer, bufferSize, kCFStringEncodingASCII) else {
        return nil
      }
      return String(utf8String: buffer)
    }
    return charsetName
  }

  init?(fromNameInLegacyWay charsetName: String) {
    // 1. Convert `String` to `CFString`
    let cfStrEncName: CFString = charsetName.withCString { (cString: UnsafePointer<CChar>) -> CFString in
      return CFStringCreateWithCString(nil, cString, kCFStringEncodingASCII)
    }

    // 2. Convert it to `CFStringEncoding`
    let cfStrEncValue: CFStringEncoding = CFStringConvertIANACharSetNameToEncoding(cfStrEncName)

    // 3. Check whether or not it's valid
    guard cfStrEncValue != kCFStringEncodingInvalidId else {
      return nil
    }

    // 4. Convert `CFStringEncoding` value to `String.Encoding` value
    self.init(rawValue: CFStringConvertEncodingToNSStringEncoding(cfStrEncValue))
  }
}
What's the problem of the current solution?


It is complicated to use multiple CF-functions to get a simple value. That's not Swifty.
CF-functions are legacy APIs that don't sometimes fit with the times.
CF APIs are officially unavailable from Swift on non-Darwin platforms.

Proposed solution

Solution is simple.
We introduce a computed property that returns the name and an initializer that creates an instance from a name as below.
extension String.Encoding {
    public var name: String? { get }
    public init?(name: String)
}
Detailed design

This proposal refers to "Character Sets" published by IANA and to "The Encoding Standard" published by WHATWG.
While the latter may claim the former could be replaced with it, it focuses on Web browsers (and their JavaScript APIs).
Since Swift APIs should be a little more universal ¹, here we consult both.
How to compromise

Not to be too arbitrary, this proposal stipulates these principles:

Focus on the encodings that are available publicly on swift-foundation at this point.

Exception: Consider compatibility for possible additions (or exposure) of ISO-8859-* encodings in the future. ²


Treat encodings as different ones if their rawValues differ.
Keep affordance: String.Encoding(name: someEncoding.name!) == someEncoding is supposed to be true.
CF compatibility is on a best-effort basis.

What's changed from legacy names?


Upper-case letters are used if desirable.
String.Encoding.shiftJIS.name returns "Shift_JIS" since "CP932" is no longer available for a name of any encodings.

Name to String.Encoding

This proposal provides a rule for converting names to String.Encodings in order to conform the principles aforementioned.
At first glance, it may look convoluted, but the results obtained from the rule are apprehensible.
The Rule

Definitions


'input matches IANA charset "foo"' means that the given input matches the name or one of the aliases of IANA charset specified by "foo" using "Charset Alias Matching" method.
'input matches WHATWG encoding "bar"' means that the given input matches one of the labels of WHATWG encoding specified by "bar" case-insensitively.
'input is "baz"' means that the given input matches case-insensitively "baz".

Procedures


If input matches IANA charset "US-ASCII" or "ISO_646.irv:1983", return .ascii.
If input is "ascii", return .ascii.
If input matches IANA charset "ISO-8859-1", return .isoLatin1. 
If input matches IANA charset "ISO-8859-9", return nil (or it should be .isoLatin5 if exists).
If input matches IANA charset "TIS-620", return nil (or it should be .isoLatinThai if exists).
If input matches IANA charset "ISO-10646-UCS-2", "UNICODE-1-1", or "UTF-16", return .unicode.
If input is "ucs-2" or "unicode", return .unicode.
If input matches one of WHATWG encodings below (except already matched above), return a corresponding String.Encoding instance :

"EUC-JP" → .japaneseEUC
"UTF-8" → .utf8
"Shift_JIS" → .shiftJIS
"ISO-8859-2" → .isoLatin2
"windows-1251" → .windowsCP1251
"windows-1252"  → .windowsCP1252
"windows-1253" → .windowsCP1253
"windows-1254" → .windowsCP1254
"windows-1250" → .windowsCP1250
"ISO-2022-JP" → .iso2022JP
"macintosh" → .macOSRoman
"UTF-16BE" → .utf16BigEndian
"UTF-16LE" → .utf16LittleEndian


If input matches one of IANA charsets below, return a corresponding String.Encoding instance:

"CP51932" → .japaneseEUC
"EUC-JP" → .japaneseEUC
"UTF-8" → .utf8
"Adobe-Symbol-Encoding" → .symbol
"Windows-31J" → .shiftJIS
"ISO-8859-2" → .isoLatin2
"windows-1251" → .windowsCP1251
"windows-1252" → .windowsCP1252
"ISO-8859-1-Windows-3.0-Latin-1" → .windowsCP1252
"ISO-8859-1-Windows-3.1-Latin-1" → .windowsCP1252
"windows-1253" → .windowsCP1253
"windows-1254" → .windowsCP1254
"ISO-8859-9-Windows-Latin-5" → .windowsCP1254
"windows-1250" → .windowsCP1250
"ISO-8859-2-Windows-Latin-2" → .windowsCP1250
"ISO-2022-JP" → .iso2022JP
"macintosh" → .macOSRoman
"UTF-32" → .utf32
"ISO-10646-UCS-4" → .utf32
"UTF-16BE" → .utf16BigEndian
"UTF-16LE" → .utf16LittleEndian
"UTF-32BE" → .utf32BigEndian
"UTF-32LE" → .utf32LittleEndian


If input is "x-nextstep", return .nextstep.
If input is "x-mac-symbol", return .symbol.
If input matches none of the above, return nil.

NOTE: Actual implementation may contain some "by-passes" for the purpose of performance optimization.

What's changed from legacy API?


Some names that are not supported by CF are available conforming to latest standard. And vice versa.
String.Encoding(name: "Shift_JIS") returns .shiftJIS.
Inconsistency about ISO-8859-* is fixed.

For example: "ISO-8859-1-Windows-3.1-Latin-1" vs "csWindows31Latin1"


Source compatibility

These changes proposed here are only additive. However, care must be taken if migrating from CF APIs.
Implications on adoption

This feature can be freely adopted and un-adopted in source code with no deployment constraints and without affecting source compatibility.
Future directions

More encodings and their names may become available on swift-foundation.
Alternatives considered

Don't compromise

We may be able to provide the computed properties and the initializers separately for IANA charsets and WHATWG encodings.
That is:
extension String.Encoding {
    /// Returns the name of IANA charset.
    var charsetName: String? { get }

    /// Returns the name of WHATWG encoding.
    var standardName: String? { get }

    /// Creates an instance from the name of IANA charset.
    init?(charsetName: String)

    /// Creates an instance from the name of WHATWG encoding.
    init?(standardName: String)
}
Acknowledgments

Thanks to everyone who gave me advices on the pitch thread; especially to @benrimmington and @xwu.
Footnotes


You may just want to parse an old XML document on local. ↩


The Encoding Standard defines ISO-8859-1, ISO-8859-9, and ISO-8859-11 as mere labels of other encodings. That doesn't fit into even current Swift APIs. ↩
