Hello,

I'm looking for a function that counts the occurences of a given character within a string.

f('|','ab|c|d') => 2


More precisely, I need to complete a vector of strings to ensure that all elements have the same count of a "separator":

 a|b|c
 a
 |a|b|c|d

 =>

 a|b|c||
 a||||
 |a|b|c|d

I guess that scan makes use of an internal function that would do the job...


Thanks,

Marc Mamin
