Hi i have unicode type characters `a = "épaisseur4/nominalvalue"` when append this to a lits i am getting like this ```auto final = [] final.append(a) print final ``` ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/8/7/87bf29dd3d5ddf2e0dec5ea2e12cd065920f3674.png) any way to fix this ? ---

```auto a = "épaisseur4/nominalvalue" final = [] final.append(a) print final print final[0] ``` returns ```auto ['\xc3\xa9paisseur4/nominalvalue'] épaisseur4/nominalvalue >>> ``` Does that get what you want? When you reference the string item it gets decoded properly. ---

There's nothing to fix. When you print an array, it will print the `repr()` of its elements. Which gives you that character code. If you want to display the string representation instead, you can print them separately. Or make your own list-type : ```python class Array(list): def __str__ (self): elements_string = ', '.join(self) return "[{}]".format(elements_string) print Array(final) print final ``` > [épaisseur4/nominalvalue] > ['\xc3\xa9paisseur4/nominalvalue'] ---

I’ve set up an experiment transferring information from one power table to another in an effort to replicate your issue, but haven’t been successful. Here is the script I used on a button: ```auto class Array(list): def __str__ (self): elements_string = ', '.join(self) return "[{}]".format(elements_string) final = [] dataSet = event.source.parent.getComponent('Power Table 1').data for row in range(dataSet.rowCount): final.append(dataSet.getValueAt(row, "Path")) event.source.parent.getComponent('Power Table').data = system.dataset.toDataSet(['Path'], [[x] for x in Array(final)]) ``` ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/e/5/e551f41b7019c2015aee62f9c2c5d194c2efda06.png) When I push the button, I get this result: ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/2/c/2c0883f3e1169ee3d429b840124e9d0841442e4e.png) The array transfers correctly, so I’m not sure what the issue is. What is your input and expected result? Perhaps, I can adjust the experiment and help you figure this out. ---

If you’re going to iterate over the array, then there’s no point in having a custom class. The whole point of it is to override the ` __str__ ` method, which is only callable on the array itself. The elements you get when iterating are the same you’d get from a builtin python list. ---

I took the liberty of cleaning up the script a bit: ```python input_table = event.source.parent.getComponent('Power Table 1') output_table = event.source.parent.getComponent('Power Table') paths = input_table.data.getColumnAsList(x) # where x is the 0 based index of the column output_table.data = system.dataset.toDataSet(['Path'], [[unicode(p)] for p in paths]) ``` Two things to note: - I don’t use vision, so I can’t test this in real conditions - Why isn’t this a binding on `Power Table` ? edit: I don’t think the explicit unicode conversion is actually needed there, but I have no idea how vision tables treat things… I’d try without it first if I were you. ---
