how to get rid of squares in the table

I noticed there are squares after the country name which shouldn't be there (shown in the attachment picture):

If you have an understanding of PHP it was probably because of this:

 [2] => Array
        (
            [0] => Afghanistan
				
            [1] => Albania
				
            [2] => Algeria
				
            [3] => American Samoa

Code (markup):

There is the space between the countries.
That code derived from:

 $string = '<SELECT NAME="country" style="border: 1px solid #990000; font-family:Arial,Helvetica,Univers,Zurich BT; ">
				<OPTION SELECTED VALUE="US" >United States
				<option value="AF">Afghanistan
				<option value="AL">Albania
				<option value="DZ">Algeria
...
			</SELECT>';

preg_match_all("#<option value=\"([^\"]+)\">([^<]+)#", $string, $foo);

print_r($foo);  //value in foo[1], contents and foo[2] 

PHP:

 

Those squares are non-printable characters like tabs or line feeds.

I think the problem is with the select statement. The option tags aren't closed.

Try this:
$string = '<SELECT NAME="country" style="border: 1px solid #990000; font-family:Arial,Helvetica,Univers,Zurich BT; ">
<OPTION SELECTED VALUE="US" >United States</option>
<option value="AF">Afghanistan</option>
<option value="AL">Albania</option>
<option value="DZ">Algeria</option>
...
</SELECT>';


To remove the existing squares try this:
UPDATE Table
SET Column = REPLACE(REPLACE(Column, CHAR(13), ''), CHAR(10), '')
