Function __global->fix_bad_unicode
Definitions
sources/global3.php
- Fixes bad unicode (utf-8) in the input. Useful when input may be dirty, e.g. from a txt file, or from a potential hacker.The fix is imperfect, it will actually treat the input as ISO-8859-1 if not valid utf-8, then reconvert. Some limited scrambling is considered better than a stack trace.This function does nothing if we are not using utf-8.
