[Gretl-devel] Missing escape character?

I see that if I have a series with an underscore in the name, for example, "PNB_SPAIN" and I make a graph and pass it to the graph page, the underscore is interpreted as making a subscript (only for one character, the S in this example) in the graph page. I guess this is unintentional and there is probably an escape character missing somewhere right? I have seen this in my gretl from current git (Ubuntu 20.04) and some other (don't konw exactly which gretl version) on  windows of a colleague here. -- Ignacio Díaz-Emparanza Departamento de Métodos Cuantitativos Universidad del País Vasco - Euskalherriko Unibertsitatea, UPV/EHU Tfno: (+34) 94 601 3732
