Octal  234 is decimal 156, and there is no character encoded there.
182 is not octal...

Did you think those escapes were decimal?  I got

Warning messages:
1: font width unknown for character 156
2: font width unknown for character 130
3: font width unknown for character 152
...

which might have given you a clue.

*You* should just be able to type those characters on a Polish keyboard,
at least if it is generating what my tables think is latin2.
