The csquotes package does a very good job automatically placing quotation marks instead of dumb quotes in the input. This works well in many languages (e.g. English, or Lithuanian ), however there is a case that it does not currently handle. That is the case when to closing quotes fall together. In Balto-Slavic languages, such as Latvian, Russian, or Belarusian this leads to unbalanced quotes, e.g.

  работа В.И. Ленина «О карикатуре на марксизм 
  и об «империалистическом экономизме»

That is

  The paper by V.I. Lenin «A caricature of Marxism 
  and «Imperialist Economism»

Note two opening quotes and only one closing quote.


работа В.И. Ленина "О карикатуре на марксизм 
и об "империалистическом экономизме"

would cause

! Package csquotes Error: Unbalanced groups or invalid nesting.

I have come up with a small hack that seems to place the quotes correctly in my documents, however it would be nice to have a general solution.

Here is what works for me. It is based on the following observation:

Closing quotes are the ones followed by a space or a punctuation mark, and all other quotes are opening quotes

This rule can be implemented using \new@ifnextchar command from amsgen.sty that does not ignore spaces:


To bind this \smartquote to the double quote character one could use a method making double quote active:

  \catcode`\"=\active %

Now to override babel definitions \setupsmartquotes can be used in \AtBeginDocument and after \selectlanguage for languages that make double quotes active.


This would produce the expected result:
