=== Lehner–Czech modification ===
An unofficial modification used in software developed by [[Michael Lehner]] and [[Peter R. Czech]]. It replaces three mathematic symbols with [[guillemet]]s and the [[section sign]] which are commonly used in the Russian language. (Lehner and Czech created a number of alternative character sets for other European languages as well, including one based on [[CWI-2]] for [[Hungarian language|Hungarian]], a [[Kamenicky encoding|Kamenicky]]-based one for [[Czech language|Czech]] and [[Slovak language|Slovak]], a [[Mazovia encoding|Mazovia]] variant for [[Polish language|Polish]] and a seemingly-unique encoding for [[Lithuanian language|Lithuanian]]. The modified row is shown below.
