“character-list” is one or more characters with no delimiter between each character
and enclosed in quotation marks. For example, to specify the split characters a, b,
and c, use the following option:
SPLITCHAR="abc"
When multiple split characters are specified, each character in the list is treated as a
separate split character unless the specified characters appear consecutively in the
value. In that case, all of the specified split characters together are treated as a single
split character.
If the value does not contain any of the specified split characters, a split does not
occur.
Default
Values are not split.
