if I copy some string to the clipboard:

echo -n 'sometext' | xclip -selection c

then

xclip -selection clipboard -o -t TARGETS

the result I get is

TARGETS 
UTF8_STRING

however if I copy ‘sometext’ the normal way, i.e. copy+c from some text editor then

xclip -selection clipboard -o -t TARGETS

displays

TIMESTAMP
TARGETS
MULTIPLE
SAVE_TARGETS
UTF8_STRING
COMPOUND_TEXT
TEXT
STRING
text/plain;charset=utf-8
text/plain

why is this?
