[Vm-dev] primitiveClipboardText mangling line endings

[Levente Uzonyi]

Nice find. The textenc parameter works. I found this in the man page of 
squeakvm:

    -textenc enc
                  specifies the external  character  encoding  to  be  used  by
                  Squeak    when   exchanging   clipboard   text   with   other
                  applications.   The  default  is  UTF-8  on  Mac  OS  X and
                  ISO-8859-15 (aka Latin9) on other Unix systems. Note that X11
                  applications   requesting   the   selection   converted   to
                  UTF8_STRING  data will (correctly) receive the clipboard text
                  encoded as UTF-8, regardless of this setting.
                  Squeak recognizes a subset of the encoding names  defined  by
                  the  IANA.  (If  you prefer to use the international currency
                  symbol rather than the Euro symbol in external text then  you
                  might want to set this to ISO-8859-1, aka Latin1.)

So the default encoding is Latin9, but that doesn't make any sense to me.
