Hi,
I have the same problem.
My files have an IBM850 encoding. After I had open the file, in the status line it says "Encoding: CP1252". On "document->set encodings->" it is UTF-8.
The two lines from my geany.conf after closing:
FILE_NAME_0=606;strakon;0;35;1;1;0;C:\ebt\kt800.pro;0;4 FILE_NAME_1=0;strakon;0;16;1;1;0;C:\ebt\kt800-1.pro;0;4
The first file I have reload with IBM850 and it is OK after reopen geany. The second file could not be loaded.
Default encoding for new files is: ISO-8859-15 Default encoding for non-unicode files is: IBM850 (The checkbox between these two options is set)
pref_editor_default_new_encoding=ISO-8859-15 pref_editor_default_open_encoding=IBM850
The debug messages: 08:41:52: Geany INFO: Geany 0.21, German_Germany.1252
08:42:07: Geany INFO: Trying to convert 18662 bytes of data from CP1252 into UTF-8. 08:42:07: Geany INFO: Converted from CP1252 to UTF-8. 08:42:08: Geany INFO: C:\ebt\kt800-1.pro : strakon (CP1252)
file->properties -> Encoding: CP1252
Best regards Gregor
