Symbols missing when using Firefox on Linux

It may be, that if you are using the admin interface of Blogless from Linux, that some symbols are missing. Just install the Symbola font to make these unicode symbols available:

For Ubuntu and Mint Linux users:

sudo apt-get install ttf-ancient-fonts

For Gentoo users:

emerge symbola

For Fedora users:

yum install gdouros-symbola-fonts
