Sample.ImportFromCSVFile cannot manage unicode descriptions

[mbaudin47]

What happened?

I want to load this file: simulations.csv.txt.

The header is:

"Pmax (bar)";"Tmax (°C)"

Reading the data file with ImportFromCSVFile fails, because of the unicode character "°".
The workaround is to use:

"Pmax (bar)";"Tmax (deg C)"

How to reproduce the issue?

import openturns as ot
print(ot.__version__)

sample = ot.Sample.ImportFromCSVFile("simulations.csv.txt")

On output, the data is:

data_0	data_1
141.3877	61.15868
338.3609	102.0516

We see that the descriptions are lost.
