You can use built-in functions like
echo()
md5()
str_split()
str_word_count()
strlen()
substr()

If your SMF is already utf8, and you're using php, no conversion is necessary.  Just copy the string.

One exception would be if there are 4-byte utf8 chars in the source data, e.g., emojis.  SMF still uses mysql's older limited utf8 implementation that does not support those.  Those would need to be detected & converted to html entities.  If you run into this, you can use SMF's routines to do so.

I would call reloadSettings(), and experiment with:
$smcFunc['htmlspecialchars']() and $smcFunc['fix_utf8mb4']()

The utf8_encode() function is an inbuilt function in PHP which is used to encode an ISO-8859-1 string to UTF-8. Unicode has been developed to describe all possible characters of all languages and includes a lot of symbols with one unique number for each symbol/character.
