Strange Characters in front of Tickers

I noticed strange characters in front of two tickers. Ticker is appearing correctly in information window. Though I am not facing issue with this , I am just curious why this happened? Here are the screen shots for the ticker " 3MINDIA"


Apparently you imported that yourself. Such strange characters are probably present in the ASCII file you are importing (it can be UTF-8 header too)

I don't know how this happened. May be I have to stop importing the data from text files and start using .csv files to avoid such errors.

Do I have to delete both the tickers and re import them again to rectify this ? or is there any alternative?

Thank you

CSV is a text file. Examine the file that you are importing with hex editor. Most likely those characters are in the file.
