Germany is denoted by 1 letter

[jellevanwezel]

In the list of countries (mrz/base/countries), all countries are denoted with 3 letters except Germany which is denoted with the single letter D while acording to: ISO_3166-1 it should be DEU

Yes, it's correct.

Germany (Deutchland) is an exception according to ICAO documentation (page 24).

You can check it yourself by searching Google images

The thing is that the documentation is confusing now, because it says it expects 3 letters while in reality only for Germany it wants 1 letter.

ICAO doc:

CODES FOR NATIONALITY, PLACE OF BIRTH, LOCATION OF ISSUING STATE/AUTHORITY AND OTHER PURPOSES Part A — Letter Codes The following are the two- and three-letter codes for entities specified and regularly updated in [ISO 3166-1], with extensions for certain States and organizations being identified by an asterisk. The current version of the codes may be obtained from the [ISO 3166] maintenance agency - [ISO 3166/MA], ISO’s focal point for country codes.

Then we will have to complain to ICAO :)

It's just an exception, my friend... just that (like United Kingdom "GB")
