I came across a web page [1] that quoting from a publication published by the Sierra Leone government indicates that this script contains 195 characters. If true, this would require thirteen rows and not the twelve envisaged by the roadmap. However, the solution would seem simple enough. Expand the tentatively planned Mende block by one row and shift the Bassa block over one row. This would also give a tentative assignment to the entirety of the U+11BXX block. Since a one row block would seem to be unlikely to be independently assigned., I don't think that this move would harm anything, even if it should prove unnecessary.
(Sorry, no details on the script at that site, but the number given does not make me think that they were counting the numerous glyph variants that the script has.) [1] http://www.sierra-leone.org/heroes7.html Ernest Cline [EMAIL PROTECTED]
