val is_normalized : t -> boolval make : encoding:encoding -> string -> (t, Rresult.R.msg) resultmake ~encoding x returns an encoded word according encoding (Quoted Printable encoding or Base64 encoding). x must be a valid UTF-8 string. charset of encoded word will be, by the way, "UTF-8".
NOTE: If you expect to generate an encoded word with something else than UTF-8 (like latin1), we decided to not handle this case and just produce valid UTF-8 contents in any cases.
Alias of make but raises an Invalid_argument if it fails.
