scanf 'I' I18N flag undocumented
Last modified: 2009-11-02 18:50:56 UTC
Reading vfscanf.c, _IO_vfwscanf looks for an 'I' conversion flag and looks for
locale-dependent digits only if it is present. The manual makes no mention of
this flag, implying by extension from other input functions that the locale
lookup always happens.
