[ruby-core:41956] [ruby-trunk - Bug #5855][Rejected] inconsistent treatment of 8 bit characters in US-ASCII

From: Yui NARUSE <naruse@...>
Date: 2012-01-07 10:49:08 UTC
List: ruby-core #41956
Issue #5855 has been updated by Yui NARUSE.

Status changed from Open to Rejected

U+0080 of Unicode can't be mapped to 0x80 of US-ASCII.
In US-ASCII, the codepoint 0x80 exists, but doesn't define any character.

Bug #5855: inconsistent treatment of 8 bit characters in US-ASCII
https://bugs.ruby-lang.org/issues/5855

Author: John Firebaugh
Status: Rejected
Priority: Normal
Assignee: 
Category: 
Target version: 
ruby -v: ruby 1.9.3p0 (2011-10-30 revision 33570) [x86_64-darwin10.8.0]


=begin
Does Ruby allow 8 bit characters (127-255) in a US-ASCII encoded string, or not?

   "\u{80}".encode("US-ASCII")      #=> Encoding::UndefinedConversionError
   0x80.chr("US-ASCII")             #=> "\x80" (US-ASCII encoding)
   "".encode("US-ASCII") << 128     #=> "\x80" (US-ASCII encoding)
   "".encode("US-ASCII") << 128.chr #=> "\x80" (ASCII-8BIT encoding)
=end
