Python error at delineation step: 'utf-8' codec can't decode byte 0xcd in position 136: invalid continuation byte

[Валерій Осипов]

Hello!

I have Python error during DEM processing ('Create streams'):

'utf-8' codec can't decode byte 0xcd in position 136: invalid continuation byte

The full message log is below.

I've just installed QGIS3.22.15-Białowieża and QSWAT3_9 (QSWAT version: 1.6.0). Before I used QSWAT+ on other computer.

              File "C:\Users/Валерий/AppData/Roaming/QGIS/QGIS3\profiles\default/python/plugins\QSWAT3_9\QSWAT\delineation.py", line 534, in runTauDEM1

I've tried to install QSWAT3_9 for everyone, but recieve the same error but different byte's position. Also, I tested Robit DEM but the result was the same.

              File "C:\PROGRA~1/QGIS32~1.15/apps/qgis-ltr/./python/plugins\QSWAT3_9\QSWAT\delineation.py", line 534, in runTauDEM1

Hello Valeriy,

I have found the same problem when trying to create streams from my dem file. Did you find an answer to your problem?

Thank you for your time!

Best wishes, Gabriel.
