Hi Graham,

For the avoidance of doubt, are you recommending we change the current text:

Optional parameters:
charset  this parameter is required when transferring non-ASCII data. 
If present, the value of charset is always UTF-8.

into


Optional parameters:
charset  this parameter is mandatory. The value of charset is always UTF-8.


Thanks,
Luc
