If nsplit is set to a non-zero positive integer, then a maximum of nsplit split points are randomly chosen for each of the mtry variables within a node. The split rule is applied to the randomly chosen split points, and the node is split on that x-variable and split value yielding the best split statistic as measured by the split rule.

A similar solution was suggested in Splitting numbers before nsplit was discussed for numeric variables. But how about when the codes are not of the same length but is separated by a character, such as a hyphen: 8-18-18-02183100-02-O-B and 8-18-018-02183100-02-O-B. In this case, split would be helpful.
