That's unreadable because of indecipherable characters like "¡�".

I suspect you're working with strings, too. That is, did you mean

temp = {{"CEST-01-A-01", "CEST-17-A-06"},
     {"CEST-01-A-02", "CEST-01-A-06",
      "CEST-02-C-06", "CEST-03-B-03",
      "CEST-03-G-07", "CEST-05-C-11",
      "CEST-06-A-09", "CEST-08-B-07",
      "CEST-09-A-02", "CEST-12-A-06",
      "CEST-12-G-11", "CEST-16-C-02",
      "CEST-16-H-04", "CEST-17-A-04",
      "CEST-18-D-05", "CEST-19-C-01",
      "CEST-19-D-04", "CEST-19-G-01",
      "CEST-20-C-09", "CEST-20-G-08",
      "CEST-22-D-07", "CEST-22-D-11",
      "CEST-23-C-09", "CEST-26-G-08",
      "CEST-27-E-04", "CEST-27-E-12",
      "CEST-30-C-08", "CEST-30-E-03",
      "CEST-34-C-06", "CEST-34-F-04",
      "CEST-35-G-09", "CEST-36-A-01",
      "CEST-36-B-01", "CEST-37-F-03",
      "CEST-37-F-06", "CEST-45-A-10",
      "CEST-45-H-05", "CEST-46-D-03",
      "CEST-46-D-11", "CEST-48-D-01",
      "CEST-48-E-01", "CEST-50-E-09",
      "CEST-51-A-01", "CEST-51-C-09",
      "CEST-53-G-01", "CEST-54-C-12",
      "CEST-54-H-11", "CEST-55-E-01",
      "CEST-55-G-06", "CEST-57-C-12",
      "CEST-57-E-12", "CEST-59-F-05"},
     {"CEST-01-A-04"}};

rather than what you posted, without quotes?

Post in InputForm by either converting cells to InputForm (select the cell and select menu options Cell>Convert to>InputForm, or select the cell and push Ctrl-Shift-I) or use the "Copy as InputForm" palette:
