And I prefer tar, cat and pipes not to mess with the contents of my files except when told to. Problems are no better or worse on Linux. Well, perhaps a bit worse, since Windows NT has quite good Unicode support. Windows application are in general better at supporting 'foreign' conventions than either MacOS or Unix applications (with some editors like Emacs as notable exceptions). But you miss the point completely. In a mixed file system environment, applications have no way of inferring which convention to follow re. linebreaks, except not to mess them up. I.e., if a 'text' file appears to use \xA as record separator, write that; if \xD\xA, write that; if \xD, write that. For new files, you have to ask the user or infer from a broader context than 'the current OS'. BTW, if you are told that a file is a 'text' file, which encoding do you expect it to use ? 7-bit encoding, ISO 646-1973 IRV (any other in widespread use?) 8-bit encoding, UTF-8, IBM CP-437, MS CP-1252, ISO Latin 1..n, etc. 16-bit encoding, UTF-16, various Japaneese, Chinese, Korean etc. IMHO, the only thing that 'text' files have in common is that you can expect some sort of record separator.

In that particular case, you wouldn't want to open the file in text mode. But there are plenty of other cases where text mode does make sense. -- Want to unsubscribe from this list?
