Haxe vs Unicode (en)
2 likes1,542 views
The document discusses the introduction and features of Haxe with an emphasis on Unicode support, including pattern matching and type inference. It highlights methods for UTF-8 and UTF-16 encoding and decoding, as well as indexing by code points and code units, while addressing current issues with Haxe's API for Unicode. The author proposes enhancements for better support and usability of Unicode features in the Haxe API.

- 12. How about the present API?
- 14. haxe.Utf8 provides methods for UTF-8 indexing by code points NOT ue cross platform API
- 15. haxe.Utf8 decode converts om UTF-8 to ISO-8859-1 encode converts oppositely both have Sing -> Sing pe
- 17. haxe.Ucs2 UCS-2 is deprecated now lack of surrogate pairs support What called as “UCS-2” is actually potenally ill-formed UTF-16 We MUST support UTF-16
- 18. encode/decode model Nave Sing haxe.Ucs2 decode process haxe.Ucs2 encode Nave Sing too complecated… hard to ansfer om legacy codes
- 19. Unifill
- 20. Unifill model Nave Sing process with Unifill methods Nave Sing intuive! easy to ansfer usable without knowledge
- 21. Unifill using unifill.Unifill; class Hello { public static function main() { trace("Hello, 世界🌏”.uLength()); } } 1010 10
- 22. TODO Propose Unifill to the Haxe API Present API is insufficient Refine the implementaon Speed Usabili
