Hi all, while working on a fix[1] for bug #80259[2], I noticed that iconv_mime_decode() and mb_decode_mimeheader() collapse all whitespace after a case folding marker (CRLF) to a single space[3]. This appears to be in violation of RFC 5322, section 2.2.3:
| Unfolding is accomplished by simply removing any CRLF | that is immediately followed by WSP. imap_utf8() properly keeps the whitespace. (ext/imap is not available on 3v4l.org) I wonder whether it's worth to fix it, due to the obvious BC break, or whether we want to treat that as a documentation issue. If we're going for a fix (what I would suggest), which version should that target?
