From: "kddnewton (Kevin Newton) via ruby-core" Date: 2024-10-21T08:50:12+00:00 Subject: [ruby-core:119538] [Ruby master Feature#20792] String#forcible_encoding? Issue #20792 has been updated by kddnewton (Kevin Newton). Yeah I'm saying it doesn't require a mutable string because it just checks the current string, it doesn't require a dup/allocation. So this avoids having to allocate a new string to check if it's possible. ---------------------------------------- Feature #20792: String#forcible_encoding? https://bugs.ruby-lang.org/issues/20792#change-110154 * Author: kddnewton (Kevin Newton) * Status: Open ---------------------------------------- I would like to add a method to String called `forcible_encoding?(encoding)`. This would return true or false depending on whether the receiver can be forced into the given encoding without breaking the string. It would effectively be an alias for: ```ruby def forcible_encoding?(enc) original = encoding result = force_encoding(enc).valid_encoding? force_encoding(original) result end ``` I would like this method because there are extremely rare but possible circumstances where source files are marked as binary but contain UTF-8-encoded characters. In that case I would like to check if it's possible to cleanly force UTF-8 before actually doing it. The code I'm trying to replace is here: https://github.com/ruby/prism/blob/d6e9b8de36b4d18debfe36e4545116539964ceeb/lib/prism/parse_result.rb#L15-L30.
