[Freeciv-Dev] (PR#12701) Polish cities Ascii bug and city selection bug

["Peter Schaefer" <peter.schaefer@xxxxxxxxx>]

Client is rc1 win32
The situation is that I built a few polish cities, including
Bialystok. I try to build a new city, and I already switched check the
preference box where it says ask for city name, because I encountered
this problem before.

Two or three bad things happen:
-the game tells me: You already have a city called Bialystok.
 this is the message for the automatically chosen name.
 however, the game is unable to choose another name but Bialystok
automatically, at least choosing a different name seems to have a
small chance only of happening.

- the game says " Only ASCII or ruleset names are allowed for cities."
  It says this for the autoselected name (from the ruleset for polish?!)

- finally the game does neither generate a random name, or popup a
blank city naming dialog, (as I tried to force by checking the "ask
for city name" box) which would have worked around the problem.

To make things worse, sometimes, maybe in Ai mode, it accepts the
apostrophe in G´dansk
