libboost-nowide1.81-dev 1.81.0-5.3 (armhf binary) in ubuntu mantic

 This package forms part of the Boost C++ Libraries collection.
 .
 The library provides an implementation of standard C and C++
 library functions which are UTF-8 aware on Windows without
 requiring to use the Wipe API.
 .
 On POSIX platforms, where UTF-8 is already commonly used, the
 calls in Nowide just alias to their standard counterparts.
