Subject: * object.c (rb_inspect): raise the result is not compatible with  
 the default external encoding. [ruby-core:42095] [Bug #5848]   If the default
 external encoding is ASCII compatible, the encoding of   inspected result
 must be compatible with it.   If the default external encoding is ASCII
 incomapatible,   the result must be ASCII only.
