My point is not to output broken utf-8 if we can. If someone
accidentally puts a UTF-8 character in core.commentChar, it will
produce broken utf-8 templates that editors might react, but hard to
see by eye. Something like this may give sufficient protection:
diff --git a/config.c b/config.c
index aefd80b..b6f73e0 100644
--- a/config.c
+++ b/config.c
