Hello Folks,


Usually we encounter a scenario where a program goes for a dump due to conversion errors while using Open/Read Dataset to read .txt files lying on the Application server.For ex below is the screenshot of such a dump.If the text file is very large then it will be tough to identify the rows or columns having non Unicode characters or identifying if at all there are any non-unicode characters in the file.

Below are the steps to identify non-unicode Characters in a .txt file :-

  • Open a blank notepad.
  • Type the below given text in the notepad.

<?xml version="1.0"?>
<test>
</test>

  • Copy the content of the .txt file on the Application Server in between the <test> and </test> in the notepad file that we had created and save it with .xml extension.
  • To identify the Non Unicode characters we can use either Google Chrome or Mozilla firefox browser by just dragging and dropping the file to the browser.
  • Chrome will show us only the row and column number of the .txt file where the non-unicode character is lying but it will not show the content of that particular row or column.

  • Mozilla Firefox will show us the row and column number along with the content of that row and column.An underscore will be till the column where the non-unicode character is lying.If there are multiple non Unicode characters in the .txt file then we should remove the first non-unicode character that was identified and then repeat all the steps as explained here to identify the next non-unicode character.Tedious,but this way atleast we can identify the presence of non-unicode characters in the text file.

  • Using Internet Explorer when we try to open the .txt file with non-unicode characters it will just show a blank page.So,we need either Chrome or Mozilla Firefox browser to identify the row and column with non-unicode characters.
  • Attached are the text file and xml file which can be used to test by dragging and dropping in Chrome or Mozilla.
