Hello everybody,
I would like to ask a simple question (probably a simple question).
I am using Stata 12.1 for Linux-64 bit and dealing with Turkish characters in string variables. I convert these Turkish characters (ı, ş, ü etc) to readable equivalents (i, s, u etc). Doing this with the code below:

foreach v of var AD {
           replace `v'=regexr(`v', "`=char(195)'+`=char(135)'","C")
           replace `v'=regexr(`v', "`=char(196)'+`=char(176)'","I")
           replace `v'=regexr(`v', "`=char(195)'+`=char(167)'","c")
           replace `v'=regexr(`v', "`=char(195)'+`=char(182)'","o")
           replace `v'=regexr(`v', "`=char(196)'+`=char(177)'","i")
           replace `v'=regexr(`v', "`=char(196)'+`=char(158)'","G")
           replace `v'=regexr(`v', "`=char(196)'+`=char(159)'","g")
           replace `v'=regexr(`v', "`=char(195)'+`=char(156)'","U")
          replace `v'=regexr(`v', "`=char(195)'+`=char(188)'","u")
          replace `v'=regexr(`v', "`=char(197)'+`=char(158)'","S")
          replace `v'=regexr(`v', "`=char(195)'+`=char(150)'","O")
          replace `v'=regexr(`v', "`=char(197)'+`=char(159)'","s")
}

However, this code cannot accomplish the conversion at the first time. Therefore, I have to do it 5 to 10 times to get a (0 real changes made) message.
My question is: can I make this loop run automatically until I get the (0 real changes made) message which indicates that all characters are converted.

Any help will be appreciated
