处理会话列表/昵称里的Emoji符号有问题
问题： 昵称里有Emoji符号，解析出来会有乱码，比如我一个群聊的房间名称叫 "机器人群💪" 💪会解析出来乱码
问题出在 pure-function-helpers/xml.js 的
function digestEmoji(html) {
if (!html) {
return '';
}
return html
.replace(/<img class="(\w*?emoji) (\w*?emoji[^"]+?)" text="(.?)_web" src=[^>]+>/g, '$3') // 
.replace(/<span class="(\w?emoji) (\w*?emoji[^"]+?)"></span>/g, '[$2]'); // ''
}
我手工改一下暂时可以用，改成
function emojiCode2string(txt){
try{
return txt ? String.fromCodePoint(0x${txt.replace('emoji', '')}) : '';
}catch(e){
return '';
}
}
function digestEmoji(html) {
if (!html) {
return '';
}
return html
.replace(/<img class="(\w*?emoji) (\w*?emoji[^"]+?)" text="(.?)_web" src=[^>]+>/g, function(input, $1, $2){
return emojiCode2string($2);
}) //
.replace(/<span class="(\w?emoji) (\w*?emoji[^"]+?)"></span>/g, '[$2]'); // ''
}
使用 String.fromCodePoint(xxxx) 来处理，emoji编码从img标签的 class name里取
