Strange result from to_a

Ruby
1

I had unexpected results and could not figure out why

puts (" “…”~").to_a.inspect
returns results of " " thru “9”

m = []
(" “[0]…”~"[0]).to_a.each{|c| m << c.chr}
puts m.inspect

Is a longwinded way of getting the samne but it gives all the results

" " thru “~”

Can anyone tell me why this is so?

I also hear that to_a is to be depricated - but it is hard to figure out
what the alternatives are. Everything I found gave the same unexpeted
results.

Ok, I’m on ruby 1.8.6
Might be time to upgrade.

Thanks

Yep, upgraded and the problem is gone.

That’s because “9”.succ is “10” instead of “:”

Only Object#to_a is deprecated.
