| 43 | <h4>Description</h4>\r | |
| 44 | <p>When FatFs is configured for Unicode API (<tt><a href="config.html#lfn_unicode">FF_LFN_UNICODE</a> >= 1</tt>), character encoding on the string fuctions, <tt>f_putc</tt>, <tt>f_puts</tt>, <tt>f_printf</tt> and <tt>f_gets</tt> function, is also switched to Unicode. The character encoding <em>on the file</em> to be read/written via those functions is selected by <tt><a href="config.html#strf_encode">FF_STRF_ENCODE</a></tt>. The Unicode characters in multiple encoding unit, such as surrogate pair and multi-byte sequence, cannot be written with this function.</p>\r | |

When <tt>FF_USE_STRFUNC == 2</tt>, a <tt>'\n'</tt> is output as <tt>'\r'+'\n'</tt>.</p>\r |
