Defect Report #309

Submitter: WG21

Subject: Clarifying trigraph substitution

Summary

Obviously, "before any other processing" is already implied by the phases of translation, but it doesn't hurt to point out the implication here. And in general, a distributive description ("each" with singular) tends to be less ambiguous than a collective one ("all" with plural). The motivation for deleting the phrase "in a source file" is, as far as I can see, weak at best.

Suggested Technical Corrigendum

Change 5.2.1.1p1:

All occurrences in a source file Before any other processing takes place, each occurrence of one of the following sequences of three characters (called trigraph sequences¹²⁾) are is replaced with the corresponding single character.
