Re: [Soaplite-devel] CPAN RT #32952 (UTF8 Strings Not Marked as UTF8 If Base64 encoded)

[Paul K. <pau...@ya...>]

Martin,

I also prefer option 1. As far as I understand, it would only
(potentially) impact non-UTF aware clients/servers. Would it be
better to add an option and keep the existing behavior by default,
but allow users to turn the base64 encoding off?

Paul.
