Update-Help does not work if the provided locale is a partial match (i.e. parent) of the available one. This means that if en-US is available, you have to provide exactly en-US and cannot just do en. I believe this is a bug for 2 reasons:
- It Makes Sense™ that if user says "I want to use English locale", they mean "Any English variant will do", not "I want to use English not associated with any country".
Update-Help with implicit locale has mechanism to fall back to parents. That is, if you don't provide explicit -UICulture, it uses the system, e.g. en-GB, then if that fails it tries en. The described bug means that fallbacks will always fail, unless the module uses exactly locale en without any country suffix, which they never do.
This can be fixed by changing string.Equals to string.Contains or some other function in UpdatableHelpInfo.IsCultureSupported.
Expected behavior
> Update-Help -Module 'Microsoft.PowerShell.Core' -SourcePath 'assets' -Force -UICulture 'en-US'
> Update-Help -Module 'Microsoft.PowerShell.Core' -SourcePath 'assets' -Force -UICulture 'en'
> # No error reported means success
Actual behavior
> Update-Help -Module 'Microsoft.PowerShell.Core' -SourcePath 'assets' -Force -UICulture 'en-US'
> Update-Help -Module 'Microsoft.PowerShell.Core' -SourcePath 'assets' -Force -UICulture 'en'
