Details
This function
reads characters that are in the current SAS session encoding and
converts them to Unicode encoding.
Example
The following
example demonstrates the functionality of the UNICODEC function:
length str4 $20;
dai=unicode('\u5927');
str1=unicodec("ABC");
str2=unicodec("ABC",'esc');
str3=unicodec(dai, 'ncr');
str4=unicodec("ab",'paren');
str5=unicodec(dai, 'ucs2');
str6=unicodec(dai, 'ucs2b');
str7=unicodec(dai, 'ucs2l');
str8=unicodec(dai, 'ucs4');
str9=unicodec(dai, 'ucs4b');
str10=unicodec(dai, 'ucs4l');
str11=unicodec(dai, 'utf8');
str12=unicodec(dai, 'utf16');
str13=unicodec(dai, 'utf16b');
str14=unicodec(dai, 'utf16l');
Results:
str1=414243
str2=414243
str3=
str4=str5=2759
str6=5927
str7=2759
str8=27590000
str9=00005927
str10=27590000
str11=E5A4A7
