It seems that whenever there is a non ASCII character in string, string concatenations are not correctly done: only the left part of the string is actually returned. I got this problem when using non ASCII character in squirrel code, and also with AI*::GetName functions which return localized names.

For instance this code :

AILog.Info("test " + AIIndustry.GetName(industry_id) + " test");

may print

test Fradworth Centrale Électrique

in french but

test Fradworth Power Station test

in english.
