Bug? special chars count as 3 chars?

[pstein]

When I search for overlong filenames I got results beginning with

D:\misc\.....

In the result list these files are listed as

D%3A%5Cmisc%5C....

So ":" is counted as 3 (!) chars "%3A" Similarly "\" as "%5C"

Can this be true?

I though such special chars need only 1 byte (in Latin charset) and hence count only for 1 in the length calculation

Can you verify this?
