So in this aspect it is not better than Grep: it is still impractical to search through files that have different encodings. > In any case, if one takes the pre-processing route, the end encoding > will be UTF-8. But then the pre-processor will have to guess the encoding (if it is not the same for all the files), which we know is not simple.
