This is driven by the format of the citation required by the institution or journal.
For example, the APA has guidelines for computer software references and, if these are to be followed, then the output from LaTeX needs to produce the appropriate format. An example they give (reference entry 92 for computer software) is
Miller, M. E. (1993). The Interactive Tester (Version 4.0) [Computer
software]. Westminster, CA: Psytek Services.
but there are a lot of precise rules for different categories of software. In many cases the software is not put into a reference entry but just mentioned in the text with its proper name and version number (see Publication Manual of the American Psychological Society (5th edition, 2001), p.280)

Bibtex is not really unicode aware. In order to use extended characters, you need to use the standard Tex replacements.
You might however want to use biblatex for a better management of bibliographic styles; and maybe have a look at biber, which aims to become a unicode aware Bibtex replacement.
