in 1994, the ideographic rapporteur group agreed to include sino-vietnamese characters in unicode. in 1993-2001, the han-nom institute assembled a collection of 9,299 “nôm ideographs" in four sets. these are the v0, v1, v2, and v3 characters shown below. a sino-vietnamese character is first assigned a v source code, and later a codepoint. these codes are used to transmit and store the character electronically. an appropriate font must be installed to render them.
