Notes:

The parameters and documentation were standardized for use in various languages written in Latin, Greek and other related scripts. If a particular letter, or all letters, don't need a parameter, please ignore it.

These parameters should not be adapted in anyway to conform with various cases of the same letter; therefore, both entries X and x would use the same parameters.

sc: The script code of the letter, for categorization and formatting purposes. When this parameter is empty or omitted, the default script from Module:languages is used.
upper: The upper case form.
upper2: A second upper case form.
lower: The lower case form.
lower2: A second lower case form.
mixed: The mixed case form of a ligature or digraph, comprised of both upper case and lower case letters.
