Comment 23 for bug 51554

I don't read Russian but the roughly translated article via Google translate seems to have some errors.

It seems to suggest that Firefox does not use curly apostrophes which is false. If you search the document for flat quotes the first such instance is "A Christmas Carol" and if you search for the curly quotes the characters are correctly matched.

Alignment issues are going to be limitations of the monospace fonts on the OS. If a character is not found in a monospace font and is found in a proportional font browsers will use the proportional font thus breaking the alignment.

All the issues in the page I see look to be from monospaced fonts for my OS (Win7) failing to have the glyphs required by the document.
