+ have no way to do this at present. A decent compromise is to print
+ all characters as if they were in the host execution character set,
+ and not attempt to recover any named escape characters, but render
+ all unprintables as octal escapes. If the host and target character
+ sets are the same, this produces relatively readable output. If they
+ are not the same, strings may appear as gibberish, but that's okay
+ (in fact, it may well be what the reader wants, e.g. if they are looking
+ to see if conversion to the target character set happened correctly).
+
+ A special case: we need to prefix \, ", and ' with backslashes. It is
+ correct to do so for the *host*'s \, ", and ', because the rest of the
+ file appears in the host character set. */
