Title: Remove BOM

Byte-Of-Mark has to be always avoided.
It can leads to a lot of misbehaviours with headers sent to the client.

This PR converts the files to UTF8 Without BOM.

Indeed the test:
```
EngineeringTest::testBESSELI with data set #1 (-1, 6, 2.2488660949282E-5)
```
Was affected by BOMs, and now it passes.
