Bugzilla

With Klaus' comment 30 patch along with Ping's patch I can now save-as emails on linux within folder names
gds-ää-envoyés
Skråp-bucketﾤ

The 2nd one has a non-Latin1 char U+FFA4 which is 3 bytes 0xEF 0xBE 0xA4.

The filenames I see for these are:
gds-ää-envoyés.msf
Skråp-bucketﾤ.msf

Unfortunately I also see these phantom files getting created too alongside the "good" files:
gds-ää-envoyés.msf
Skråp-bucketﾤ.msf
The 2nd one took a bit longer to appear.

In the imap log, the "proposed url" seems to show utf8 strings (that get sent to imap server):

2021-01-15 22:03:16.428539 UTC - [Parent 33443: Main Thread]: D/IMAP proposed url = Skräppost--åeds folder for connection Skråp-bucketﾤ has To Wait = false can run = false
2021-01-15 22:03:16.428594 UTC - [Parent 33443: Main Thread]: D/IMAP proposed url = Skräppost--åeds folder for connection gds-ää-envoyés has To Wait = false can run = false

And for the "currentURL" imap log shows % encoded:

2021-01-15 22:03:14.217789 UTC - [Parent 33443: IMAP]: I/IMAP 0x7f91a2d32800:imap.gmail.com:NA:ProcessCurrentURL:imap://w4k9vws%40gmail%2Ecom@imap.gmail.com:993/select%3E/Skr%C3%A5p-bucket%EF%BE%A4:  = currentUrl

Of course, the folder names are encoded in imap strings and sent as correct utf8, e.g.:

2021-01-15 22:03:14.740320 UTC - [Parent 33443: IMAP]: I/IMAP 0x7f91a2d32800:imap.gmail.com:A:SendData: 6 select "Skråp-bucketﾤ"

Finally, I just noticed that messages with well-defined .jpg attachments show the attachment inline OK but there are no links at the bottom for downloading the attachments. Don't know what is causing this. So, I can't check if the patch(s) affect attachment downloads.

Edit: I just reverted both patches back to trunk with "hg shelve" and can now see attachment links and save .jpg attachments OK. Putting the patches back (hg unshelve) and now I can't see the attachment links again.
