Talk:Farey sequence

REXX program encoding

What language encoding should the file be saved in, and what should the LC_* env vars be before invoking Regina on a Unixy OS? Currently under UTF-8 everything, Regina (-v: REXX-Regina_3.6(MT) 5.00 31 Dec 2011) complains:

    10 +++    say center('Farey sequence for order '   n   " has"   #   'fractions.', 150, '═')
Error 40 running "/tmp/test.rex", line 10: Incorrect call to routine
Error 40.23: CENTER argument 3 must be a single character; found "═"

It goes away after changing that "═" to any ASCII char. The same problem is present in many Rexx examples on this site. --Ledrug (talk) 21:30, 1 April 2014 (UTC)
