Question

I have a CSV file supplied from a client which has to be parsed and inserted into a database using PHP.

Before inserting the data into the DB, I want to convert it to UTF-8 but I cant seem to find how.

This is what I got trying to detect the files encoding:

$ enca -d -L zh ./artigos.txt 
    ./artigos.txt: Universal character set 2 bytes; UCS-2; BMP
    CRLF line terminators
    Byte order reversed in pairs (1,2 -> 2,1)

I tried using the iconv function but it messes up the conversion and shows the result with diferent characters than the originals.

First line of the file (base64 encoded):

Answer 1

This seems to work(little endian), althoug you didnt include any non ascii chars

$t=base64_decode($s);
echo iconv('UCS-2LE', 'UTF-8', substr($t, 0, -1));//last byte was invalid
