%global common_description_en \
The VSS-Text (as an abbreviation for Virtual String Subsystem Text) library is \
designed to provide advanced string and text processing capabilities. It \
offers a convenient and robust API that allows developers to work with \
Unicode text, regardless of its internal representation.
