#47033 [NEW]: converting binary<->string without charset translating

From: lunter at interia dot pl Operating system: all PHP version: 6CVS-2009-01-08 (snap) PHP Bug Type: Unicode Engine related Bug description: converting binary<->string without charset translating Description: ------------ converting binary<->string without charset translating Two functions for converting binary<->string without translating charset needed. It is very usefull because binary data can consists utf-8 substring, you need to convert to string type. Also when you have to see binary representation of utf-8 string, or operating on it as binaries. Example 1: You have (binary)$b. It consists two bytes: 11001110 10110010 Its length in binary representation is two. It is also valid one-length UTF-8 char(946) (greek small letter beta) How to conver it ($b) into one-char UTF-8 string?? When we try $u=(string)$b, it gives two-char UTF-8 string. Example 2: You have (string)$u UTF-8 one-char string. It consists chr(946) (greek small letter beta) Now You have to see two bytes binary representation of this (11001110 10110010). There is no way to convert it without charset translation...
