About the PasDoc bug on src/ui/castletiledmap_map.inc : I found the issue.

Short version: Please add to Debian a patch to remove UTF-8 BOM from
these 2 files:


This will make them work with latest stable PasDoc. From what I
tested, no other files should need it.

Longer explanation:

- Old PasDoc indeed had problems with UTF-8 BOM in include files.

    We fixed it in
, followed by https://github.com/pasdoc/pasdoc/commit/2bc326bb4eb4e587c5b42cf9422e8d2f30aade96
, but it is not released as stable PasDoc yet.

- And it looks like we introduced at some point UTF-8 BOM into these
include files. Probably because Delphi (proprietary Pascal compiler
that we also now support) likes to add UTF-8 BOM. These include files
contain a Polish character in the name of contributor "Tomasz Wojtyś",
this likely provoked some software (maybe Delphi) to add or require
UTF-8 BOM there.

- For FPC, there's no need for BOM, so in Debian you can just remove the BOM.

- Of course at some point I plan to also release latest PasDoc with
this fix officially :)

My tests:

$ stable/pasdoc castletiledmap.pas --include ../common_includes/ --output=/tmp/

Warning[2]: Error EPasDoc: Invalid character ("", code 239) in Pascal
input stream (at castletiledmap_map.inc(1)) while parsing unit
castletiledmap.pas, continuing...

$ sed --in-place $'1s/^\uFEFF//' castletiledmap_control.inc
$ sed --in-place $'1s/^\uFEFF//' castletiledmap_map.inc

(sed trick from https://stackoverflow.com/a/45240995 )

$ stable/pasdoc castletiledmap.pas --include ../common_includes/ --output=/tmp/
... now goes OK

Procesing complete CGE ("./mk_docs.sh html") with old PasDoc now works
OK too, so I think these were the only 2 include files affected.
