Many of the Radar Vectoring Charts for airports in countries such as Poland and Latvia etc include a note concerning cold weather correction to altitudes. Either the chart lists two different values for (I think) ISA and ISA - 20 deg C or there is a statement that the altitudes shown assume ISA - 20 deg C.

The Ops Manual of the company I fly for contains guidance and instructions to correct for low temperature.

Incidentally corrections should be made to Decision Altitudes/Heights, Procedure Altitudes and Minimum Flap Retraction Altitudes as well.
