Downcasing strings
Read OriginalThe article details the author's experience trying to downcase a large UTF-8 text file with Polish characters using standard Unix tools like `tr` and `dd`. It highlights the poor or non-existent support for multibyte characters in these tools and contrasts them with working solutions in `gawk` and `sed`. An update notes that `tr` on OS X/BSD handles this correctly.
