UnicodeDecodeError: 'utf-8' codec can't decode byte 0xe8 in position 63: invalid continuation byte

I have the following error message every time I try to open a meteorological data file (loaded from the Copernicus program) using the plugin UMEP in QGIS. How can I fix it? I am a beginner in Python.

the meteo file is attached here,
meteo.zip

UnicodeDecodeError: 'utf-8' codec can't decode byte 0xe8 in position 63: invalid continuation byte

Please attach your file so that I could tryit out.

You are trying to use a netCDF-file directly into UMEP. That is not possible. You should convert it into a text file and then run it through a MetDataProcessor OR download ERA5 data via the ERA5 Download tool in UMEP which will convert nc-files directly into UMEP-formatted meteorological files.

yes sir, i used the ERA5 Download tool to download my data, but the result is a nc-file not converted into UMEP-formatted files.

The tool should have created the nc-files AND a text-file. Are you sure that no text file was created? Can you make a screen dump of the settings when using ERA5 Download.

you are right sir, I found my error. thank you so much.
