On Alpine this is because iswblank in UTF-8 locales is the same as isblank in the C locale. This means it only returns 1 for U+0009 TAB and U+0020 SPACE. I haven't looked at the others, but assume the situation is similar. I am thinking of fixing this in Gnulib since I think the proper behavior of iswblank in a UTF-8 locale is to return 1 for U+2002 EN SPACE and U+2003 EM SPACE. This is because they are just altering the size of the SPACE character [1] [2]. Collin [1] https://en.wikipedia.org/wiki/En_(typography) [2] https://en.wikipedia.org/wiki/Em_(typography)
