# availableStringEncodings Returns a zero-terminated list of the encodings string objects support in the application’s environment. ``` class var availableStringEncodings: UnsafePointer { get } ``` ## Return Value A zero-terminated list of the encodings string objects support in the application’s environment. ## Discussion Among the more commonly used encodings are: - [`NSASCIIStringEncoding`](/documentation/Foundation/NSASCIIStringEncoding) - [`NSUnicodeStringEncoding`](/documentation/Foundation/NSUnicodeStringEncoding) - [`NSISOLatin1StringEncoding`](/documentation/Foundation/NSISOLatin1StringEncoding) - [`NSISOLatin2StringEncoding`](/documentation/Foundation/NSISOLatin2StringEncoding) - [`NSSymbolStringEncoding`](/documentation/Foundation/NSSymbolStringEncoding) See the [`NSStringEncoding`](/documentation/Foundation/NSStringEncoding) type for a larger list and descriptions of many supported encodings. In addition to those encodings listed here, you can also use the encodings defined for CFString in Core Foundation; you just need to call the function to convert them to a usable format. --- Copyright © 2026 Apple Inc.
