Howto Use Custom Delimeters in Data Import

Hello,
I am trying to import data with customized separators.
A data column contains commas. This always results in the column being separated at the comma. The attempt to use customized separators does not work. The default delimiter for the export from Infomix DB is the “|” pipe. This does not work. Is there a hint how this can be changed - Manual? I tried anything to stop create a new column when komma appears in data.
