That would be expected to work

(in a UTF-8 locale || on Windows)
&& on a device with Unicode support
&& in a font that has the glyph.

(it works on Windows because we fake much of a UTF-8 locale there).

There is an alternative: dagger _is_ in the standard Adobe character 
set, so this will work as something \206 (untested) in 8-bit Windows 
character sets on windows(), postscript(), pdf() ... devices

As ever, the information asked for in the posting guide helps us give 
a better answer.

But the Adobe Standard encoding does.
