hmmm… depends on the font being used because not all font types will display certain characters where others might. This is more of a font issue, so if there is a specific character(s) that are part of a word, you will want to make sure that font can support it. What and where does this Greek word show up that is not displaying properly?
Thanks for the link… it appears you have some kind of scripting to hide the source code, so it was very hard to dig into the code but unable to really find much. However, the theme’s style.css is using this:
PT Sans is the font being used, then if that is not available on the user’s computer, then it goes to Arial, then for anyone on a MAC, it will then use Helvetica…
This is where you might want to test the different fonts. I’m not sure if PT Sans supports Greek characters or not, but Arial should (I think). Fonts and what they can and cannot display is up to the font being used, so you will want to make sure whatever you choose, to ensure a compatible font is used. Still, Arial should work. Perhaps it might have something to do with your translation plugin (scripts) or something else? Disable any translation or language plugins you might have and see what happens?
Sorry I cannot be much more help on this… hopefully you will be able to find a solution. However, I just grabbed your PDF, copied that portion of text content, installed Preference on my local test site, then added it to a sample page. You might be interested in seeing this:
What this tells me is that there is something unique to your site’s setup that is perhaps conflicting with the displaying of your Greek characters, or perhaps if you copied this content from another source, perhaps that is causing the issues. greek_2014-03-27.jpg
I just updated my last post to say perhaps it was the method of pasting that content into the page from whatever source you got that from? Either way, something has caused a conflict with the displaying of those characters.
