That's not the way to obtain the length (i.e., number of elements) of an array. See scalar. See also the discussion in Scalar values (in perldata) in the paragraph beginning 'The length of an array is a scalar value.' Dunno about the rest of your question.

>perl -wMstrict -le "my @ra = qw(a b c); print length @ra; print scalar @ra; ;; @ra = (); print length @ra; print scalar @ra; " 1 3 1 0

[LanX]: (not a high priority bug because I can use some HTML entities in the second string)
[Corion]: base64 is padded to a multiple of 4 chars (or something)
[LanX]: misunderstanding, I joined them before converting to base64
[Corion]: Also, I would be wary of encodings and try to make really sure that both input strings are UTF-8. Maybe join the input strings from one source together to see whether they decode as bad or not
[Corion]: LanX: Then the problem should persist without encoding to base64 too ;)
[LanX]: I think it's a flag problem ... I'll produce a reprodocable example for SOPW
[Corion]: "flag problem" to me sounds like "contains UTF-8 bytes but was never properly decoded to an UTF-8 string"
[LanX]: not my code ...
[choroba]: yeah, sounds like one of the strings is not flagged as UTF-8
[choroba]: which usually means its input wasn't handled correctly
