Subject: util/base32: loosen the precondition forbidding unicode and requiring str -- now... 
X-Git-Url: https://git.rkrishnan.org/pf/content/en/service/somewhere?a=commitdiff_plain;h=dde2376c4e2d85ba2dc8a9b71f44a17682d49574;p=tahoe-lafs%2Ftahoe-lafs.git

util/base32: loosen the precondition forbidding unicode and requiring str -- now it requires either unicode or str
Hopefully this will make it so that tests pass with François Deppierraz's patch to fix the tahoe cli's handling of unicode argument.
