New issue 1656 by [email protected]: Reconsider naming scheme of
String::IsAsciiRepresentation and String::IsAsciiRepresentationUnderneath
http://code.google.com/p/v8/issues/detail?id=1656
As the comment for String::IsAsciiRepresentation says:
// Returns whether this string has only ASCII chars, i.e. all of them can
// be ASCII encoded. This might be the case even if the string is
// two-byte. Such strings may appear when the embedder prefers
// two-byte external representations even for ASCII data.
this method does not give any indication about the representation, but
about the content. String::IsAsciiRepresentationUnderneath however returns
the actual representation, taking into account that the underlying string
(in cons and slices) may have different encoding.
On the other hand, String::IsTwoByteRepresentation and
String::IsTwoByteRepresentationUnderneath should return the same, since
there is no case where a cons string's underlying string is converted from
twobyte to ascii, correct?
