XKB symbols / utf-8 help?

[Jonathan D. Proulx]

First if anyone can point me to a better list for this I´ll happily
take it the, but I though given the wide geographic range of Edububtu
users someone has probbaly dealt with similar issuse.

I´m trying to develop a Navajo localization.  My first step is setting
up a keyboard layout.  In addition to the standard latin alphabet I
need: 

Łł Ńń Áá Éé Íí Óó Ąą Ęę Įį Ǫǫ Ą́ą́ Ę́ę́ Į́į́ Ǫ́ǫ́ Ǫ́ǫ́

Fiddling with the xkb/symbols/us I developed a variant based off
us(intl) that will do ą, ę, į, and all the acute accents using the
dead_acute.  I cannot combine the dead_acute with the ogoneks and for
some reason oogonek and lstroke don´t work and default to the
definition in us(intl).  I´m typing in a utf-8 xterm which I know can
display the characters since I can copy and past from know utf-8
sources.

Any pointers?
