Yes, it is possible. This is an example: perl -C -E'say"\x{e8f4}\x{e8f5}"'
Screenshot: <http://i.imgur.com/wivY9.png> The magic happens not at the Perl level, but at the rendering step. I first picked two unassigned codepoints. Unicode provides a private use area for exactly this kind of purpose. I also took care not to trample over a [registered script] (http://enwp.org/ConScript_Unicode_Registry). Then I created a font with two glyphs, `U+E8F4 ROTATED LATIN CAPITAL LETTER D` and `U+E8F5 LATIN CAPITAL LETTER A WITHOUT COUNTER`, and installed it. Last, I restarted my terminal application so that the new font gets picked up, and executed the Perl one-liner from above.
