I can't figure out how to get through this problem about UTF-8 conversion.

  • Hi everybody,
    I can’t figure out how to get through this problem about UTF-8 conversion.
    Here’s the steps:

    1. Open a ANSI text file (.txt or .php)
    2. The text does not have any special or accented characters
    3. Convert text into UTF-8 without BOM
    4. close file
    5. re-open same file: it’s again ANSI

    What should I do in order to write PHP encoded as UTF-8?

    P.S.: If text does have special or accented characters, it correctly encodes into UTF-8.
    Version of notepad++ is 7.2.2 32bit

    I don’t think you have a problem. I am fairly certain that if a file does not contain any special characters, then the ANSI and the UTF-8 without BOM versions are identical.

    Under Settings->Preferences->New Document Encoding, select UTF-8 and also check the Apply to opened ANSI files box. Then when you open your “non-special” text file, NPP will tell you it is UTF-8. But, in reality, it is both UTF-8 and ANSI.

  • if you set the encoding to UTF-8 wihtout BOM, the file without any UTF-8 encoded chars will be physical the same like an ansi file. NPP will open the file in the default charset as there is nothing encoded in it.

    Using UTF-8 with BOM will add 3 chars to the document that might apear in the page if you include files - maybe thats your reason to use without BOM.

    i am adding following code in PHP:

     # UTF8 check: öäüßÖÄÜ にほんご

    then save it as UTF-8 without BOM
    NPP will identify the UTF-8 encoded japanese/german mix and recognise the document as UTF-8 without BOM.
    please be aware that you need to mark the html-output as UTF-8 to avoid browsers to show rubbish.

    header("Content-Type: text/html; charset=utf-8");
    ?><!DOCTYPE html>
    		<meta charset="UTF-8">
