Hi all,

I want to download a file and unzip the only file in the archive to feed a CSV.File (Energy data for a France region from [https://eco2mix.rte-france.com/download/eco2mix/eCO2mix\_RTE\_Auvergne-Rhône-Alpes\_En-cours-Consolide.zip](https://eco2mix.rte-france.com/download/eco2mix/eCO2mix_RTE_Auvergne-Rh%C3%B4ne-Alpes_En-cours-Consolide.zip)).  
I know that the unzipped content is encoded in Windows-1252. I have been able to download, unzip and CSV.read other files from the same source.  
When I **manually** open (using my computer OS) the archive, it seems that the problematic archive has non-UTF8 character in the file name within the archive (not only in the unzipped archive content).

```julia
using ZipFile, HTTP

dl_buffer = IOBuffer(HTTP.get("https://eco2mix.rte-france.com/download/eco2mix/eCO2mix_RTE_Auvergne-Rh%C3%B4ne-Alpes_En-cours-Consolide.zip", retries=10).body)
ZipFile.Reader(dl_buffer)

```

But I get an error:

```julia
ERROR: ArgumentError: Invalid utf8 string: UInt8[]
Stacktrace:
 [1] utf8_validate(vec::Vector{UInt8})
   @ ZipFile ~/.julia/packages/ZipFile/6aqG6/src/ZipFile.jl:206

```

Any idea on how to open it correctly?  
Thx

Problem solved. I have used InfoZIP package and it works like a charm.  
But I still have no clear reason of why this difference.
