FieldtypeDecimal: "Warning: 1265 Data truncated for column 'data' at row 1"

[dynweb]

When trying to save a field with FieldtypeDecimal, I get the following error:

Warning: 1265 Data truncated for column 'data' at row 1

And as usual, it seems to be an issue with decimal and thousands separator -- I use "," as decimal and "." as thousands separator.

The problem seems to be here: https://github.com/processwire/processwire/blob/44fcf13ea2d7f14a04eed54c29afcc79eb46ec45/wire/modules/Fieldtype/FieldtypeDecimal.module#L75

When the value is sanitized, PW only looks for ".", not for ",". As soon as I change the above line (and the next one) to ",", everything works. 

Can someone confirm? Or did I miss something?

Thank you.

After further investigation, I come up with this one:
