Questions tagged [strings]
{strings} are sequences of characters (most commonly literal constants). However TeX doesn't have the same concept of strings as other languages, so for questions regarding text in general this tag does not apply. Usually when dealing with {strings} one also uses the primitive {pdfstrcmp} or dedicated packages, such as {xstring} or {expl3}'s string module (l3str).
