-** This function is to be used to decide which encoding algorithm we should

-**
-** Arguments are:
-**
-** ascii       - Number of ASCII characters in to-be-encoded string.
-** specials    - Number of ASCII characters in to-be-encoded string that
-**                still require encoding under quoted-printable.  Note that
-**                these are included in the "ascii" total.
-** eightbit    - Eight-bit characters in the to-be-encoded string.

-** Returns one of CE_BASE64 or CE_QUOTED.
