A proposal was posted by Michael Everson for the Blissymbolics script to be included in the Universal Character Set (UCS) and encoded for use with the ISO/IEC 10646 and Unicode standards.[14] BCI would cooperate with the Unicode Technical Committee (UTC) and the ISO Working Group. The proposed encoding does not use the lexical encoding model used in the existing ISO-IR/169 registered character set, but instead applies the Unicode and ISO character-glyph model to the Bliss-character model already adopted by BCI, since this would significantly reduce the number of needed characters.[citation needed] Bliss-characters can now be used in a creative way to create many new arbitrary concepts, by surrounding the invented words with special Bliss indicators (similar to punctuation)[citation needed], something which was not possible in the ISO-IR/169 encoding.
