My understanding: Because LCL wanted to benefit from new possibilities in
version 3.0.0 (e.g. use functionality newly provided by the RTL instead of
certain own alternative routines), but the previous LCL code included some
assumptions (like that all ansistrings should always contain UTF-8) which
may not always be the case in FPC RTL by default (e.g. certainly not for
MS Windows applications). But again - they could continue using the
original code as it was if they wanted to do so.
