[cl-smtp-devel] Encoding issues

[Leslie P. Polzer]

Hi,

I'm having trouble getting my German umlauts and other
special characters across the SMTP pipe.

Without any effort by me, some parts get annotated inline:

  Sei gegrüßt -> Sei gegr=?ISO-8859-15?Q?=FC=DFt

and some vanish completely:

  benötigt -> bentigt

I tried converting my UTF8 strings to latin1 via flexi-streams
and Babel:

  (babel:octets-to-string
    (babel:string-to-octets
      "Sei gegrüßt, benötigt"
      :encoding :utf-8)
    :encoding :latin-1)

-> "Sei gegrüßt, benötigt"

but CL-SMTP refuses the body with:

  debugger invoked on a FLEXI-STREAMS:FLEXI-STREAM-ENCODING-ERROR
    in thread #<THREAD "initial thread" {A72A5D9}>:
  #\VULGAR_FRACTION_ONE_QUARTER is not in this encoding.

Partial backtrace:

0: (FLEXI-STREAMS::SIGNAL-ENCODING-ERROR
    #<FLEXI-STREAMS::FLEXI-8-BIT-OUTPUT-STREAM {B35E001}>
    "~S is not in this encoding.")

    :END
    NIL)

Also, latin1 seems to be hard-coded at a bunch of locations
in CL-SMTP.

I'm using Hans' BKNR version of CL-SMTP and would
appreciate any help.

  Cheers,
