How Encode SQL_Latin1_General_CP1_CI_AS

Question

I readed to Encoding SQL_Latin1_General_CP1_CI_AS into UTF-8. Despite trying all of the writings, it never happened.

I am using php 7.1

Example:

$str = iconv('UCS-2LE', 'UTF-8', $str);
$str = iconv('CP1252', 'ISO-8859-1', $str);
$str = iconv('CP850', 'UTF-8//TRANSLIT", $str);

Output :

䅋䅐ⵋ䙅⁅䅒䥋传䕚⁌䅔䅓䥒⁍䅍呎剁䥌䬠偁䭁
EFEYAÞÜZÜM
KOL├Ø- 70cl S├ØL├ØN.K.x6AD

wrong characters appear.In the meantime I am using Turkish characters.

Regards.
