Change default omission for truncate/excerpt to Unicode "…"


I’d love some feedback on whether it would be a good idea to change the default omission for the Rails “truncate” and “excerpt” helpers from three full stops ("…") to a Unicode ellipsis ("…").

I like how this only uses one character instead of three. Depending on the font, it can use up less visual space than three separate full stops would. I usually override the default

The obvious downside is that someone would use the helper in a non-Unicode context and find this default behaviour problematic. I’m not sure to what extend Rails is comfortable assuming that strings are Unicode.

I found this old (2010-ish) ticket with some positive discussion around it (, but I’m not sure if it ended up in Rails and was later removed or what.
