http://www.macchiato.com/unicode/convert.html has UTF, RACE and LACE conversions, with a bit better error checking.
http://www.macchiato.com/unicode/charts.html has Unicode charts, plus a new "filter" on the left.
http://www.macchiato.com/unicode/show.html lets you type or paste in Unicode text, and see GIFs (in case fonts are missing).
Feedback is welcome, though I make no apologies for the simple GUI.
(Paul noted that someone had registered "BQ--3AADEABQAAYAAMQAMYAGSADGABQ4NVFU3THPLTTUW" with VGRS. My program says it's an error -- it appears to have an extra W at the end. The source text appears to be hangul: 퀀퀲퀀퀰퀀퀰퀀퀲퀀큦퀀큩퀀큦퀀큡킶탔킴탔탎탵탎클)
