I am using a commercial sever with FreeBSD system without root account. I install gnuplot with my account. But, I can not set up fonts. So, I copy the fonts files in my home
Here are all prerequisites for printing UTF-8 characters with gnuplot
:
set encoding utf8
enhanced
must be available and set for the chosen terminal type: set terminal … enhanced …
Failing to observe the last point, results in the following gnuplot
error:
Unable to convert "…�…": the sequence is invalid in the current charset (UTF-8),
falling back to iso_8859_1
This situation may occur when transferring plot files from Microsoft Windows™ to GNU/Linux.
The character encoding of the plot definition file can be checked with the following GNU/Linux command:
$ file -bi bad.plt
text/plain; charset=iso-8859-1
To correct the character encoding of the plot definition file, use this command:
$ iconv -f iso-8859-1 -t utf-8 -o good.plt bad.plt
