Pgaccess - localization problem

Please help me with pgaccess localization! I use the PosgtgeSQL
as a base RDBMS for my students in a course of database development. I have set the
russian.koi8-r localization and the koi-8 fonts, in the setup form, but have
got nothing effect?
Thats the first problem, but the main problem is an impossibility
of input russian symbols, and see the output (output's like a missing font
charset) in all pgaccess forms.

I use:

tcl/tk 8.3
Slakware Linux 7.1 2.2.18
PostgresSQL 7.0.3 (pgaccess 98.5?)
Xserver 3.3.6
the system and Xwindow propely localized. Nothing problems with russian input
and output in all Xapplications, except tcl-based (no input).
XF86config attached if needed.

I am not familiar with tcl programming, but through a couple of expirements
with modifying the intlmsg procedure, it becomes clear, that:

$Messages($msg) does't return anything independently of presenting
such element. However array get - does it properly.

proc {intlmsg} {msg} {
global PgAcVar Messages
tk_messageBox -title Archibald Warning -parent .pgaw:Preferences -message $PgAcVar(pref,language)
# Displays properly encoding - russian.koi8-r
if {$PgAcVar(pref,language)=="english"} { return $msg }
if { ! [array exists Messages] } { return $msg }
tk_messageBox -title "Debug" -message "Массив существует"
# Displays the properly encoded message?
if { ! [info exists Messages($msg)] } { return $msg }
tk_messageBox -title "Debug" -message "info after"
# that's never display's
return $Messages($msg)
}

my .pgaccessrc

pref,font_normal {-cronyx-Helvetica-Medium-R-Normal--*-*-*-100-*-*-koi8-r}
pref,font_bold {-cronyx-Helvetica-Bold-R-Normal--*-*-*-100-*-*-koi8-r}
pref,username {}
pref,autoload {1}
pref,typecolors {black red brown #007e00 #004e00 blue orange yellow pink purple cyan magenta lightblue lightgreen gray lightyellow}
pref,font_fix {-cronyx-helvetica-r-normal--*-*-*-100-*-*-koi8-r"}
pref,systemtables {1}
pref,lastport {5432}
pref,tvfont {helv}
pref,lasthost {localhost}
pref,lastdb {polic}
pref,password {}
pref,rows {200}
pref,lastusername {}
pref,language {russian.koi8r}
pref,font_italic {-cronyx-Helvetica-Medium-R-Normal--*-*-*-100-*-*-koi8-r"}
pref,typelist {text bool bytea float8 float4 int4 char name int8 int2 int28 regproc oid tid xid cid}

It seems to me - that tcl does not recognize 8-bit character?
But I have found nothing about it in manuals.

Sorry for my english.

Thank you! please answer to aidanet(at)yandex(dot)ru or aidamir(at)mail(dot)ru
