Errors converting string to float

[gitapat]

Hi!
I've been using the serval plugin to edit heightmaps and have encountered an issue, whenever negative numbers are in use in the value textbox the following converting error occurs.

2023-11-26T05:29:30 WARNING Traceback (most recent call last):
File "C:\Users/.../QGIS/QGIS3\profiles\default/python/plugins\Serval\serval.py", line 726, in set_active_raster
old_spin_boxes_values = self.spin_boxes.get_values()
File "C:\Users/.../QGIS/QGIS3\profiles\default/python/plugins\Serval\band_spin_boxes.py", line 82, in get_values
value = int(raw_val) if self.data_types[nr -1] ValueError: could not convert string to float: '−9999.0000'

I spotted the problem to the minus sign, it is for some reason unknown to me in unicode.

I'm not proficient enough in python but I did try to fix it by simply adding
raw_val = raw_val.replace(chr(8722), "-")

In band_spin_boxes.py prior to the string float converting. But it didn't work any better.

For now I manually replace the incorrect sign value in the textbox when the error occur in qgis.
