|

Very easy. Since all the characters are from ASCII you simply
|
|
zero-extend the values.

drepper$ echo 'black pearl jasmine tea' | od -t x1

0000000 62 6c 61 63 6b 20 70 65 61 72 6c 20 6a 61 73 6d

So the UCS-2 string is
|
|
|
|
0x0062, 0x006c, 0x0061, ...
|
|
|
|
You get the idea. With iconv() you have to take care of the
|
|
byte-order, though. UCS-2 can mean little- or big endian. Looking at
|
|
your result
|
|
|
|
> $9 = 25856
|
|
|
|
it shows that the other byte-order is used (25856 == 0x6500).
