@LouisGac ; i think default template must use only "well know and distributed" font.

and no external font except icon font (glyphicon and/or fa currently).

OK for 3.0 ?

I disagree - why not use custom fonts. That's why you have a fall-back where regular fonts are used. The problem here is that the particular font (Lato) is incomplete.

There is a newer version of Lato (2.0) which probably fixes this problem (it is by a Polish designer). See http://www.latofonts.com/lato-free-fonts/#download

So the goal should be to update the template accordingly.

@elissa : i make a quick test in 3.0 with copy paste some string,

But if you can send the lss file : it's more easy :)

Not same issue tha forum : http://testing.sondages.pro/answershtml/index.php/564381 we don't use bold in 3.0 next version for answertext

Polish language makes problems with most fonts.
Rather than using ugly and fonts for all languages because of polish, I think we'd rather provide an easy way to use NOTO in default template (like a line in the config.xml). So polish people could solves this problem by their own.

@LouisGac : it's the reason why i propose to use "well know and distributed" fonts by default.

We need non-latin caracter on each public template.

PS : it's not LATO (admin part) here :)

I don't think that Polish font has to be ugly. Moreover, I suppose that this is a problem not only with Polish font but some other Slavonic languages.
