由於描述中的特殊字符( ),我在下面的代碼中遇到了一個問題。由於這些特殊字符,我收到錯誤。如何刪除python中的特殊字符?
錯誤:'ascii'編解碼器無法解碼位置821中的字節0x94:序號不在範圍內(128) 請幫我刪除此錯誤。下面分別

數據以文本形式和html表單數據給出:http://m.cellularoutfitter.com/p-85870-anycom-solar-bluetooth-car-kit_c.html(在頁面的末端具有描寫的特徵)
我已經嘗試了各種方法和編碼,但失敗了。
首先我得到鏈接的完整src然後通過使用x路徑我在變量中獲得描述。 由於某些原因,我無法發佈完整的代碼。遺憾
Python代碼:
parser = etree.HTMLParser(remove_blank_text=True, encoding="utf-8")
tree = etree.HTML(popup_html, parser)
description = tree.xpath("//span[@itemprop='description' and not(src)] ")
log.debug(str(description[0]))
for desc in description:
log.debug(etree.tostring(desc,encoding='UTF-8'))
if etree.tostring(desc,encoding='UTF-8').find("IFRAME") < 0:
reply_dict['product_desc'] = reply_dict['product_desc'] + etree.tostring(desc,encoding='UTF-8')
reply_dict['product_desc'] = reply_dict['product_desc'].replace(" \n", "").replace("\n", "<br/>").replace("img","").replace('< src="/productPics/altImgs/decal-skin-pdp-2.jpg"/>',"")
reply_dict['product_desc'] = reply_dict['product_desc'].replace("\xef\xbf\xbd","'")
reply_dict['product_desc'] = reply_dict['product_desc'].replace("\x92","'")
reply_dict['product_desc'] = "<br />".join(reply_dict['product_desc'].split("\n")).replace(" ", " ").encode('ascii', 'xmlcharrefreplace')
