[Hazem_Saleh]

i found few posts here but no luck

Activities - Supported character encoding

i have this and utf-8

but when i open the file still utf-8 BOM

i think the same bug showing again

Small Bug - Read & Write Text UTF-8 encoding

Hi UiPath Team, Just small bug (maybe fixed on 2020, don’t know) but, while write txt files (UiPath Activity) with encoding “UTF-8” the resulting encoding is “UTF-8 with BOM”. I know is a super niche thing but we had some issues with SAP due to some files that had to loaded as UTF-8. Thanks, Martí

UTF-8 without BOM

@vandame welcome to the forum give a try on following: [grafik] [grafik] Ensure following: [grafik]

hi
thanks for answering i dont have parameters !

[Hazem_Saleh]

i tried the default as well!

[ppr (Peter Preuss)]

screenshot is showing the usage of Invoke Method. here you do have the parameters

@Hazem_Saleh

i tried the default as well!

within a less commented demo:

it is shown on how .Net is not offering a differentiated utf-8 as codepage / encoding name. Therefore write text will write UTF-8 with BOM (check the Preamble marks above)

With above given approach (shared link) we can write files in utf8 without BOM

Thanks im trying invoke method

i cant find WriteAllText

Error ERROR Validation Error ‘File’ does not have a public static method named 'WriteAllText ’ matching the parameter types, generic type arguments, and generic type constraints supplied to InvokeMethod ‘Invoke Method’. Framework/Process.xaml`

the screenshots are clear on the usage
give a try on following:

Ensure following:

for sure use variables for the text and path.

When further assistance is needed share with us your XAML or screenshots of your modelling and all details

Ensure that the parameters are configured correctly

@Hazem_Saleh
Let’s conclude and close:

• within .Net utf-8 codepage, webname … for the encoding is not differentiated between

  • with BOM
  • without BOM

• Using the File.WriteAllText Methods lets us specify to write text in utf-8 without BOM

@Hazem_Saleh

‘File’ does not have a public static method named 'WriteAllText ’ matching the parameter types, generic type arguments, and generic type constraints

A hint that the Invoke Code is not properly configured (e.g. the Arguments)

For the File.WriteAllText approach the relevant information was shared.

Hi
the only solutions i found is to invoke code
with system io file

invoke method never recognized the function !.

[ppr (Peter Preuss)]

@Hazem_Saleh

invoke method never recognized the function

We cannot agree on the Statement as we had implemented offen with invoke method and it is running in Production sucessfully

But for Sure WE configured and passend the Parameters defined By method signature

[Hazem_Saleh]

hi again
i still believe its a bug !

i have passed the right argument

try
{

Encoding utf8WithoutBom = new UTF8Encoding(encoderShouldEmitUTF8Identifier: false);

System.IO.File.WriteAllText(stringFilepath,stringtext, utf8WithoutBom );

}
catch (Exception ex )
{
error=ex.Message;

}

this work but if i use invoke method

[ppr (Peter Preuss)]

@Hazem_Saleh

i still believe its a bug !

still it looks to us that you have not configured the parameters ( no method with this signature exception).

We suggest to rate a bug on the usage. And usage has also to be conform with specifcations. As also already mentioned above
