The <span tag="MKIV" style="font-style:sans;">bibTEX</span> for­mat is rather pop­u­lar in the <span tag="MKIV" style="font-style:sans;">TEX</span> com­mu­nity and even with its short­com­ings it will stay around for a while. Many pub­li­ca­tion web­sites can ex­port and many tools are avail­able to work with this data­base for­mat. It is rather sim­ple and looks a bit like <span tag="MKIV" style="font-style:sans;">Lua</span> ta­bles. Un­for­tu­nately the con­tent can be pol­luted with non-stan­dard­ized <span tag="MKIV" style="font-style:sans;">TEX</span> com­mands which com­pli­cates pre- or post­pro­cess­ing out­side <span tag="MKIV" style="font-style:sans;">TEX</span>. In that sense a <span tag="MKIV" style="font-style:sans;">bibTEX</span> data­base is of­ten not coded neu­trally. Some lim­i­ta­tions, like the use of com­mands to en­code ac­cented char­ac­ters root in the <span tag="MKIV" style="font-style:sans;">ascii</span> world and can be by­passed by us­ing <span tag="MKIV" style="font-style:sans;">utf</span> in­stead (as han­dled some­what in <span tag="MKIV" style="font-style:sans;">LATEX</span> through ex­ten­sions such as <tt style="color:rgb(0,102,102);font-size:100%;" >bibtex8</tt>).
