     Type:  Bugs                     |      Status:  new    
Milestone:  To Be Determined         |   Component:  locale 
  Version:  Boost 1.49.0             |    Severity:  Problem
 Keywords:  Boost.Locale encode UTF  |  
-------------------------------------+--------------------------------------
 When passing a char output iterator (such as
 {{{std::back_insert_iterator<std::string>}}}) to
 {{{boost::locale::utf::utf_traits<char>::encode}}}, the compiler (Apple
 LLVM compiler 3.1 in Xcode 4.3 with extra warnings enabled) emits a
 warning about assigning {{{unsigned int}}} to {{{char}}}.  The code
 incorrectly attempts to write the code unit to the output as a
 {{{code_point}}} instead of a {{{CharType}}}.

 The attached patch performs a safe static cast of each code unit to
 {{{CharType}}} as it is written to the output iterator.
