Ahaaa... So the "oscillatory behaviour" is just me shifting between
machines with proper locale configuration and machines without it! I
think that isalpha() is actually the way to go. People just have to
get their locales right. Here's what's in isalpha(c)=3D=3D1 for the da_D=
K
locale:

ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz=AD
=C0=C1=C2=C3=C4=C5=C6=C7=C8=C9=CA=CB=CC=CD=CE=CF=D0=D1=D2=D3=D4=D5=D6=D8=
=D9=DA=DB=DC=DD=DE=DF=E0=E1=E2=E3=E4=E5=E6=E7=E8=E9=EA=EB=EC=ED=EE=EF=F0=
=F1=F2=F3=F4=F5=F6=F8=F9=FA=FB=FC=FD=FE=FF

The hyphen following 'z' is actually 0xad (soft hyphen).
