From 548c65a568e14490f1a6b80e92c175e2410ddf20 Mon Sep 17 00:00:00 2001 From: Rob Pike Date: Thu, 11 Apr 2013 11:33:25 -0700 Subject: [PATCH] spec: add another sentence about BOMs Although one may argue that they should be legal, gc (at least) disallows byte order marks that are not the first code point in the file. Added a sentence to the "Implementation restriction" clause in the "Source code representation" section to document this better. Lifting this restriction (again - the rule has changed at least twice already) would not break any existing programs, should we later decide yet again to fiddle the rules about these little fly specks.
