Does Tellme support “special characters” in VoiceXML?
Currently, the Tellme VoiceXML interpreter provides limited support for double-byte character encodings in VoiceXML documents. By default, the Tellme interpreter assumes that VoiceXML documents are encoded in UTF-8, which covers the normal set of ASCII characters (and more). Additional the Tellme interpreter supports the ISO 8859-1 encoding, widely used for European character sets.
