This package uses both tracklang and texosquery to look up the
locale information from the operating system and provide
commands that can access locale-dependent information, such as
the currency symbol and decimal separator. The file
tex-locale.tex provides generic TeX code. The LaTeX package
tex-locale.sty can additionally load babel or polyglossia with
the locale's language setting, as well as various other
packages such as fontspec (XeLaTeX/LuaLaTeX) or fontenc +
inputenc (pdfLaTeX).
