I am trying to decode an Azure Storage Key that’s supposedly base64 encoded, but I’m getting all kinds of wonkey characters. Example:

```
Base.decode64! "ZG2p8/z2ATu8NVLBXmeFtkX9chpkbk2EK9fH4qVKxvC//mSlIdsqzvZpNa4k7tPPR86RmiGkdi0BLwAEtPbkXA==" |> String.codepoints
```

Results in:

```
[
"d",
"m",
<<169>>,
<<243>>,
<<252>>,
<<246>>,
<<1>>,
";",
<<188>>,
"5",
"R",
<<193>>,
"^",
"g",
<<133>>,
<<182>>,
"E",
<<253>>,
"r",
<<26>>,
"d",
"n",
"M",
<<132>>,
"+",
<<215>>,
<<199>>,
<<226>>,
<<165>>,
"J",
<<198>>,
<<240>>,
<<191>>,
<<254>>,
"d",
<<165>>,
"!",
<<219>>,
"*",
<<206>>,
<<246>>,
"i",
"5",
<<174>>,
"$",
<<238>>,
<<211>>,
<<207>>,
"G",
"Α",
...
]
```

This definitely isn’t correct, or I’m not thinking about something correctly here. Is there something I need to do special for utf8 encoded strings?

Thanks for the help,

Jeramy
