<p>Coerces an arbitrary value into a buffer and then encodes the result
|
|
|
|
|
into hex as an in-place operation. Returns pointer to the resulting

|

string for convenience.</p>

|
Coercing to a buffer first coerces a non-buffer value into a string, and
|
|
|
|
|
then coerces the string into a buffer. The resulting buffer contains the
|
|
|
|
|
string in CESU-8 encoding.
