This will cause problems when exporting profiles as the GEDCOM standard uses the slash character "/" to indicate the start of the Surname in the name field (as identified by the NAME Tag). Adding extra slashes within the name will result in the Surname not being correctly picked up when importing the GEDCOM file.
"The name value is formed in the manner the name is normally spoken, with the given name and family name (surname) separated by slashes (/)."
"The surname of an individual, if known, is enclosed between two slash (/) characters."
