Reserved letters and non-letter Characters
Reserved letters are for custom terrains in user-made campaigns. In addition to these it is currently also possible to use other characters not on the above list to represent custom terrain, such as ½ § @ % etc., but new "official" terrain may be assigned for these characters in the future. So when creating custom terrain, the letters marked as reserved on the above list should be used first.
Use campaign definitions (see CampaignWML) to prevent your custom terrains from interfering with other campaigns.
The terrains will be changed from a single letter to a multi letter system. There will be a compability layer for a short while. This layer doesn't work for campaigns with custom terrains, these campaigns have to be changed to use the new system.
The following rules are stated for the new terrain letters, note most of these rules are not validated since it would slow down Wesnoth; not following these rules might break Wesnoth.
- terrain strings are between 2 and 4 characters
- terrain strings start with a capital letter and the following letters are lower case
- terrain strings can only contain letters and the symbols /|\ which are meant for directional items like bridges.
- the underscore is used for internal terrains
- the star '*' can be used for wildcards in some parts
Starting positions are defined by a number followed by 1 space and then the terrain string; this means that a starting position is no longer automatically a keep.
The letters Y,y,Z,z are reserved for UMC so any string containing any of these letters is a custom terrain. Other undefined terrain strings are reserved for future expansion within Wesnoth.
Conversion form old to new
There's a conversion perl script for map named map_convert.pl. This script will convert a map with the old letters to the new strings. Some parts still have to be done manually, here a lookup table with the letters.

Keep
The keep definition is now done with terrain transition WML,
since we're no longer out of letters, this will be done
manually. the _K is for backwards compability but this
will be removed in the near future. The _K uses the special
castle transition WML the new ones don't. This would
also allow to mix items, eg a Kh keep in a Ce castle.

Specials
These terrains are hardcoded in the game and translated
automatically. The old UMC terrains are here for backwards
compability this compability will only be guaranteed till
the next major release after 1.2.(That would be 1.4 or 2.0.)
As stated before the * will no longer be supported.
