Character Set
From Svg wiki
To properly use the utf-8 and utf-16 character sets, you need to define it in the HTTP header.
This can be done using the .htaccess file on Apache server
for utf-8
AddCharset UTF-8 .htm AddCharset UTF-8 .html AddCharset UTF-8 .svg AddCharset UTF-8 .svgz
and for utf-16
AddCharset UTF-16 .htm AddCharset UTF-16 .html AddCharset UTF-16 .svg AddCharset UTF-16 .svgz
