//! This class intended to temporary switch C locale and logically equivalent to setlocale(LC_ALL, "C").
//! It is intended to format text regardless of user locale settings (for import/export functionality).
//! Thus following calls to sprintf, atoi and other functions will use "C" locale.
//! Destructor of this class will return original locale.
//!
//! Notice that this functionality is platfrom dependent and intended only to workaround alien code
//! that doesn't setup locale correctly.
//!
//! Internally you should prefer more portable C++ locale interfaces
//! or OCCT wrappers to some C functions like Sprintf, Atof, Strtod.
