## works as expected
xyplot(1~1, key = list(text = list(c("Maenner"))))

## works as expected
xyplot(1~1, key = list(text = list(c("Maenner"))), xlab =
"M\344nner")

## gives an error
xyplot(1~1, key = list(text = list(c("M\344nner"))))

Is this a bug?

TIA,

Bernd

You forgot to mention your version, assuming 2.7.0 unpatched.

Corrected by Brian Ripley in developer version (and probably also in patched)

Well, you failed to give the 'at a minimum information' asked for in the
posting guide, and \344 is locale-specific.  I see 'MingW32' below, so 
will guess this is German-language Windows.  We don't know what the error 
was, either.

It works correctly for me in CP1252 with R-patched, and gives an error in 
2.7.0 (and works in 2.6.2).  I think it was fixed as side effect of

     o	Rare string width calculations in package grid were not
 	interpreting the string encoding correctly.

although it is not the same problem that NEWS item refers to.

My error message in 2.7.0 was

Error in grid.Call.graphics("L_setviewport", pvp, TRUE) :
   invalid input 'M?nner' in 'utf8towcs'

which is what makes me think this was to do with sizing the viewport.


So please update to R-patched and try again.
