The pipe is replaced in the short description with comma

Hi all,

we are using Algolia with magento and have observed the effect, that Algolia replaces all pipes (|) in the short desciption with commas.
So from this
Nice product | high quality | low price
we get this
Nice product , high quality , low price
As the text with the pipe is used on the product detail page, this is inconsistent.
Does this have to do with the pipe being the delimiter for multiselect facets?
Can this be configured differently, so the pipe can stay?
In the index the short description is shown like this:
“Nice product” , “high quality” , “low price”

Thanks
Jörg
