php - Character encoding issue when importing into WordPress -

i've created routine migrate content drupal wordpress. i'm querying drupal database within php script, using wp_insert_post() add together info wordpress database.

i'm having issue character encoding, after i've inserted drupal content wordpress characters cause remainder of string stripped.

take example:

<strong>the next text stop @ tick’, text stripped out</strong><br />

when importing this, after tick remove, such:

<strong>the next text stop @ tick

to seek remedy issue i've attempted alter character encoding, strips out tick, funky space-like character, characters pound £ symbol.

$html = iconv('utf-8', 'us-ascii', $html);

i've tried //translit , //ignore function, still either removes these characters or stops @ first problem.

can advise on way content format of accepted wordpress, without removing these characters, convert them alternative.

edit

i've tried passing string through htmlentities(), returns empty string.

additionally i've attempted determine encoding of string using mb_detect_encoding(), returns false, meaning cannot observe encoding.

edit 2

when view drupal database record in hex mode tick returns ’.
