Package: Portable UTF-8

Mostly we are using UTF-8 encoding in our projects and it's working, but if you need to process third party data maybe with unknown encoding it can be painfully. So here comes a auto-detection for this kind of strings.


 



In "Portable UTF-8" I have implemented a auto-detect character encoding function with support for UTF-16 and UTF-32. So for example if your customer send you a mix of UTF-16 or UTF-8 or ISO ... encoded CSVs you can detect the encoding via:

UTF8::str_detect_encoding('中文空白'); // 'UTF-8'
UTF8::str_detect_encoding('Abc'); // 'ASCII'

You can also auto-convert the encoding and this function will also try to fix broken / double encoding, so you can call this function also on a UTF-8 string and you don't mess the string.

UTF8::encode('ISO-8859-1', '-ABC-中文空白-'); // '-ABC-????-'
//
UTF8::encode('UTF-8', '-ABC-中文空白-'); // '-ABC-中文空白-'
//
UTF8::encode('HTML', '-ABC-中文空白-'); // '-ABC-中文空白-'
//
UTF8::encode('BASE64', '-ABC-中文空白-'); // 'LUFCQy3kuK3mlofnqbrnmb0t'
