metafun/label: utf8 and spaces

[Patrick Gundlach]

Hi,

is there any way to get utf-8 labels and without the 'strange' space
glyph?

--------------------------------------------------

\startMPenvironment[+]
\enableregime[utf]
\stopMPenvironment


\starttext 
foobar baz äöß  % <-- OK

\startuniqueMPgraphic{bla}
label("foobar baz äöß",(3cm,3cm));  % <-- broken
draw btex foobar baz äöß  etex  % <--- OK
\stopuniqueMPgraphic

\useMPgraphic{bla}

\stoptext
--------------------------------------------------

A follow-up/answer...
(I hate doing this)

textext is a perfect substitute for label. (see metafun-p.pdf)

I think of textext (and \sometxt) as a substitute for btex ... etex, 
not of label. I substitute of label should also accept a position 
variable, so that one could write

texlabel.top("$x^2$", origin) ;

I know this should be simple, but I do not understand the metapost 
macro language to write such a macro. Writing

label.top(textext("$x^2$"), origin) is too verbose. Suggestions?

Why not this one? (Much faster, less problems, etc.)

\enableregime[utf-8]

\starttext

\startuniqueMPgraphic{bla}
label(\sometxt{foobar baz äöß},(3cm,3cm));
\stopuniqueMPgraphic
\useMPgraphic{bla}

\stoptext

Metapost strings are something I wouldn't use anyway, although
Aditya's idea is also a nice one (a dirty way would be to redefine
label to use textext instead - I don't mean it too seriously of
course).

(with the sound of 'wizard of oz')
Because, because, because... I didn't know about it. 

Thanks!
