Ruby 1.9, YAML & encodings

Ruby
1

Hello all.

I’m trying to migrate a project to ruby 1.9.

I have a lot of source, ressource, and data files, all encoded in
ISO8859-1(5), so I’m trying to preserve this.

The trouble is that YAML seems to load every string file that contains a
non ASCII char with an encoding of “ASCII-8BIT” ; if I understand
correctly, it should follow the Encoding.default_external value.

A small example session :

13:20 fred@balvenie:~/ruby/blackops> ruby19 -v
ruby 1.9.0 (2008-07-25 revision 18217) [i386-freebsd6]
13:20 fred@balvenie:~/ruby/blackops> irb19

require “yaml”
=> true

Encoding.default_external
=> #Encoding:ISO-8859-15

txt = “\351\351\351”
=> “ééé”

txt.encoding
=> #Encoding:ISO-8859-15

z = YAML.load(YAML.dump(txt))
=> “\351\351\351”

z.encoding
=> #Encoding:ASCII-8BIT

z << “\351”
ArgumentError: append incompatible encoding strings: ASCII-8BIT and
ISO-8859-15
from (irb):62

z.force_encoding(‘ISO8859-15’)
=> “ééé”

z << “\351”
=>
“éééé”
Any ideas ?

(Nota : this is a hand compiled 1.9.0-3 version under FreeBSD, but it
does the same with the official ports version, 1.9.0-1.)
