Hello, I've just discovered an odd behavior of `fold' while trying to wrap a piece of text containing phonetic characters.
Take the following line, for example: Tcl (pronounced "tickle" or tee cee ell /ˈtiː siː ɛl/) is a high-level, It is 71 characters long. Still, running echo "Tcl (pronounced "tickle" or tee cee ell /ˈtiː siː ɛl/) is a high-level," | fold -w 72 -s produces Tcl (pronounced tickle or tee cee ell /ˈtiː siː ɛl/) is a high-level, I've had someone test this with FreeBSD's `fold', which didn't behave that way. Instead, it filled out the line as expected. Further investigation by developers of Adélie Linux revealed that GNU's `fold' is counting multi-byte utf-8 sequences (in this case, the phonetic characters) as separate columns: awilcox on gwyn [pts/11 Sun 16 19:01] ~: cat testing.txt 1234567890 234567890 234567890 234567890 234567890 234567890 234567890 /ˈtiː siː ɛl/ Adélie en français español ¿que? ¡ay! here is 70 chars ^ yep. awilcox on gwyn [pts/11 Sun 16 19:01] ~: fold -w 72 -s testing.txt 1234567890 234567890 234567890 234567890 234567890 234567890 234567890 /ˈtiː siː ɛl/ Adélie en français español ¿que? ¡ay! here is 70 chars ^ yep. msi
