az storage blob download has strange name parsing issues

[Zhaph]

Describe the bug

When attempting to download specific files from blob storage, the command fails with the error <partialfilename> was unexpected at this time.

For example the following file name is parsed successfully:
az storage blob download -n "Sitecore/10.2.0/Sitecore 10.2.0 rev. 006766 (XM) (Cloud)_cd.scwdp.zip"

While replacing the spaces with underscores:
az storage blob download -n "Sitecore/10.2.0/Sitecore_10.2.0_rev.006766_(XM)_(Cloud)_cm-fixed.scwdp.zip"
Results in:
_(Cloud)_cm-fixed.scwdp.zip was unexpected at this time.

Replacing the underscores with hyphens results in the similar message.

Replacing the underscore after rev.006766 with a space successfully attempts to download the file.

Hi @Zhaph,

2.49.0 is not the latest Azure CLI(2.50.0).

Please upgrade to the latest Azure CLI version by following https://learn.microsoft.com/en-us/cli/azure/update-azure-cli.

Thank you for opening this issue, we will look into it.

Just upgraded to:
azure-cli 2.50.0

core 2.50.0

And I can confirm the behaviour is the same.

Note - this occurs before any attempt is made to connect to the storage account, so you don't really need to supply valid creds/paths to test.
