Sigma Zeichen ersetzen

___I usually work with this regular expression:

field as an example:

field________________:TITLE
regular expression_____:Σ\b
replace matches with___:ς

I use capital and no case sensitive comparison.

___And a second one right after that which goes like this:

field________________:TITLE
regular expression_____:ς'
replace matches with___:σ'

no case sensitive comparison

___because in many cases I have a word like:

Σ'αγαπώ which turns ς'αγαπώ.
