On the company app there is an internal chat and forum where customers and others partners comunicate with us without using any e-mail service (and so we can have a control about it). The fact it's that the "plain text it's too grey and white" so my work was make possible insert emoticons and smileys on all conversations. I just create an PHP array where every :-) or :) or : ) will be replaced with the 16x16px emoticon. In fact they are hard to see so i expanded the size to 24x24 doesnt matter if the font and line height will be affected.<br/>表情符號和表情符號<br/>16x16、chat、emo、emoticons、happy、sad、small、smile、smileys<br/>16×16、聊、惡魔、表情、快樂、美國、小、微笑、表情<br/>資料來源：openclipart ( https://openclipart.org/ )
