When exporting CSV data, Unicode prefix is not properly set

[trytrytogo]

hi, i installed 1.2.12 on centos7 with mysql Ver 15.1 Distrib 10.4.12-MariaDB and rrdtool 1.7.2.

1:
i saw 1.2.12 have resolve the problem "issue#3427: When exporting to a CSV with unicode characters, contents can become garbled". i read #3427.
so i exported a data. it's wrong.
first, i use Chinese as my "User Language", my graph title name is "联通 - Polling Time". i exported data.

then, i use English as my "User Language", i exported data too.

it's a new bug or others?

2:
i found the "Interface - Traffic Data Template", in "Maximum Value" can use |query_ifSpeed|, i want to use |query_ifHighSpeed| ,it's wrong. it's a new feature?

thanks all to creat cacti.

Can you please edit:

graph_xport.php, line 211 and change:

print mb_convert_encoding($output, 'UTF-16LE', 'UTF-8');

to

print $output;

And let us know how the output looks?
