\section migration_1_4_preferences Fl_Preferences
(to be documented)
Starting with FLTK 1.3, preference databases are expected to be in UTF-8
encoding. Previous databases were stored in the current character set or
code page which renders them incompatible for text entries using
international characters.
Starting with FLTK 1.4, searching a valid path to store the preferences
files has changed slightly. Please see
Fl_Preferences::Fl_Preferences(Root, const char*, const char*)
for details.
If you want to retain user preferences you may want to move the preferences
file from its old location to the new location as documented in
Fl_Preferences::Fl_Preferences(Root, const char*, const char*) .
