Some tile sets use the accented characters for additional graphical symbols. This can make racial language text difficult to read. You can remove the accented characters and symbols from the data files. This works on existing worlds and saved games.

Since the structure of language files might change, it is safest if you remove the problem characters from the files yourself. Here are four methods to do just that. The first (Jackard's) only works on Windows, but is probably the easiest for novice users. The second (frobnic8's) will work anywhere Python does (i.e. just about anywhere). The third is a quick fix that works in Linux and the fourth is a small Windows application.

unaccented ascii. Based on the unicode hammer from:
+
latin1_to_ascii -- The UNICODE Hammer -- AKA "The Stupid American"
−
http://code.activestate.com/recipes/251871-latin1-to-ascii-the-unicode-hammer/
+
 
 +
This takes a UNICODE string and replaces Latin-1 characters with
 +
something equivalent in 7-bit ASCII. This returns a plain ASCII string.
 +
This function makes a best effort to convert Latin-1 characters into
 +
ASCII equivalents. It does not just strip out the Latin1 characters.
 +
All characters in the standard 7-bit ASCII range are preserved.
 +
In the 8th bit range all the Latin-1 accented letters are converted to  
 +
unaccented equivalents. Most symbol characters are converted to
 +
something meaningful. Anything not converted is deleted.
 +
 
 +
Background:
 +
 
 +
One of my clients gets address data from Europe, but most of their systems
 +
cannot handle Latin-1 characters. With all due respect to the umlaut,
 +
scharfes s, cedilla, and all the other fine accented characters of Europe,
 +
all I needed to do was to prepare addresses for a shipping system.
 +
After getting headaches trying to deal with this problem using Python's
 +
built-in UNICODE support I gave up and decided to use some brute force.
 +
This function converts all accented letters to their unaccented equivalents.
 +
I realize this is dirty, but for my purposes the mail gets delivered.

== The Linux way ==
 
−
 
−
Conversion between character sets is a standard part of Linux.  To convert all the files in one go, change to the "raw/objects" directory and run this command:
 
−
 
−
for f in language_*.txt; do \
 
−
  iconv -f CP437 -t ASCII//TRANSLIT $f > $f.new; \
 
−
  mv -fv $f.new $f; \
 
−
done
 
−
 
−
All accented characters are converted to their normal, non-accented versions.  Other characters (if any) are converted to their closest 7-bit ASCII representation.
 
−
 
−
This will overwrite the original language files.  If you want them back, you can always unzip them again:
 
−
 
−
unzip -j '''''path-to-zipfile''''' raw/objects/language_\*.txt
 
−
 
−
== [[User:Hermano|Hermano]]s small app ==
 
−
 
−
For Windows users there is this small [http://dffd.wimbli.com/file.php?id=2088 application] that replaces accented characters from files by just dragging & dropping the file on the application icon.
