Detailed Description

template<class traits>
struct stlencoders::portable_wchar_encoding_traits< traits >

A character encoding traits adaptor that converts an underlying encoding traits class for type char to type wchar_t.

A portable encoding traits class' encoding alphabet must only use characters from the basic execution character set:

a b c d e f g h i j k l m n o p q r s t u v w x y z
A B C D E F G H I J K L M N O P Q R S T U V W X Y Z
0 1 2 3 4 5 6 7 8 9
_ { } [ ] # ( ) < > % : ; . ? * + - / ^ & | ∼ ! = , \ " '

Template Parameters
