Quoted-Printable Encoding Stream

Wraps a StreamInterface and encodes its content as quoted-printable on-the-fly. Produces output with soft line breaks at 76 characters per RFC 2045.

Quoted-printable is preferred for text content with occasional non-ASCII characters, as it keeps ASCII text readable while encoding special chars.

Encoding rules (RFC 2045 Section 6.7):

  • Literal representation for printable ASCII (33-60, 62-126) except =
  • =XX hex encoding for non-printable and non-ASCII characters
  • Soft line breaks (=\r\n) at 76 characters
  • Trailing whitespace must be encoded
