I use evolution-data-server r8327 (I know your patch
was commited on r8322, I used trunk ;) to check all
emails on my mbox, the result is:
evolution-data-server 2.21.4: 20% emails' CJK header
can't been decode.
evolution-data-server r8327: 5% emails' CJK header
can't been decode.
evolution-data-server with my patch: 1% emails' CJK
header can't been decode.
And I use gmime (bu using
g_mime_utils_header_decode_text() function) to decode
all encoded-words on my mbox. The result is the same
as evolution-data-server r8327.
What's the different between your patch and my patch?
I think when your decoder decode the email that break
a single multi-byte character across multiple
encoded-word tokens, it ignore the byte(s) that can't
convent to UTF-8. And in my patch,
header_decode_text() will parse as many as possible
encoded-words that has the same charset and encoding,
then call rfc2047_decode_word() to decode these
encoded-words. In fact you can't simply ignore the
byte(s), because the first byte in an encoded-word can
combo with the last byte in the front encoded-word is
a multe-byte encoding character, but it combo with the
next byte can be another multe-byte encoding character
too. Here are some examples on my mbox:
=?GB2312?Q?=C4=D4=B1=D8=D0=EB=BC=E6=C8=DDLinux=B2=D9=D7?==?GB2312?Q?=F7=CF=B5=CD=B3?=
=?GB2312?Q?_=B0=B2=D7=B0=D2=BB=D0=A9=B3=A3=D3=C3=B5=C4=C8=ED=BC?==?GB2312?Q?=FE=B0=FC=B5=BDubuntu=CF=B5=CD=B3=A3=A1?=
