If there is a "use utf8;" anywhere in a Perl file, would it not be reasonable to interpret that it is describing the entire file and not just the portion of the file below that statement? Perhaps a reasonable design would be that if a file contains a UTF-8 declaration anywhere in it, the entire file is treated as such, both the part above and the part below that declaration. And if multiple conflicting encoding declarations exist for the current file, that is an error. Basically the encoding declaration can be something that is scanned for in advance of the regular parsing, or if done inline, encountering such would cause the parser to restart at the beginning if the declaration is different than what the parser was doing up to that point, effectively the whole file is affected by that declaration either way. -- Darren DuncanThread Previous | Thread Next
