*Only* if the string is treated as an ASCII key (the type of key that
gets hashed with the SSID to generate the real key).  There is no way to
treat a 26-character string as a hex WPA key; WPA keys are 256 bits
long.

I have no idea how XP's supplicant is coded, but I suspect that it
treats any string shorter than 64 characters as an ASCII key and hashes
it.  For wpa_supplicant, try putting the key in double quotes, since
that's what flags wpa_supplicant to treat the string as an ASCII key and
hash it.
