direct use of UTF-8-encoded data from Fortran

M_unicode

M_unicode provides support for Unicode encoded as UTF-8 data even
when the optional Fortran ISO_10646 extension is not provided.

A user-defined type named unicode_type allows for creating ragged
arrays of ASCII or UTF-8 encoded data that otherwise can be treated much
like a CHARACTER kind.

M_unicode has overloading for all the basic operators and character
intrinsics with both a procedural and OOP interface. The intrinsic
overloads include TOKENIZE() and SPLIT().

In addition the UPPER() and LOWER() funtions support the concept
of case for the Unicode Latin characters not just the ASCII subset,
and a basic SORT() function provides for ordering the data by Unicode
codepoint values.

The distribution provides a Make file and easily builds with fpm.

Documentation and examples provide a guide for basic usage.

M_unicode should be useful for anyone working with UTF-8 data,
particularly if the compiler does not support the UCS-4 extensions
of Fortran.
