By the way, I had a little trouble applying your Greenland patch, because it was encoded in ISO 8859-1, and even though its email header line correctly said 'Content-Type: text/plain; charset="iso-8859-1"', Git understandably took alarm at the mixture of the patch's ISO 8859-1 and tzdata's UTF-8 and refused to apply the patch. As it turned out I needed to edit the patch anyway so this was only a minor hiccup. Still, it looks like this could be a systematic problem with Microsoft Outlook and/or Exchange, and I wonder whether we can briefly advise Microsoft-using patch-senders to avoid future glitches. Unfortunately I don't use Microsoft software for email and so don't know what to suggest. Would it suffice to say "Please use 'git send-email'", or would that not work because Microsoft Exchange transcodes email from UTF-8 into ISO 8859-1? Does Microsoft Exchange transcode attachments, so even "Please send the patch as an attachment" does not work? Or was the problem here that Microsoft Outlook transcodes outgoing mail, and if so can this be fixed by asking users to specify UTF-8 encoding for outgoing messages at File > Options > Advanced > International options[1]? Any suggestions would be welcome. [1]: https://learn.microsoft.com/en-us/exchange/mail-flow/content-conversion/mess...
