2022年02月11日更新
OX-7版对文本做了如下修订：
1）与可能的牛高四“yru版”mdx词头对比，增补近200个词头；
2）与endnote版牛高四的标准词头（standard标签）对比，修订了几十个原文中不准确的法文、西班牙文单词词头；
3）与txt81网站下载的牛高4网络文档比较，增补400多个本属于衍生词部分的词头（主要是以“-”开头的词缀和“the”开头的词组，这明显属于原发布者故意删除、破坏）；
4）遗漏的繁体字“摺”替换为“折”；
5）若干其他小错误顺手修正，比如Π、π。
——到此为止，我个人发现的牛高4原始txt文本存在的主要问题已经被修正了，其他毛病还有，比如音标修订的误伤或漏改，个别漏网的繁体字，表示温度、角度等的 ° 符号，非规范法语单词“fete、cafe”等，但这些比较trivial了，容留以后慢慢修改。
请打包mdx,使用中更容易发现错误,以后更改再增加版本号。
在github传了一份牛高4文本（ GitHub - mahavivo/OX4: Errata for OALD 4th Edition ），名字比较低调（毕竟侵犯版权不好大张旗鼓）。因为此后改动的东西可能不多，用git追踪版本比较方便，我将主要用github进行日常修订，积累一定erratum后再在这里更新。
我主要感兴趣的是原始数据，txt做成mdx后要两头更新，还要照顾显示格式上的错误，很烦人的。其他人有兴趣可以制作mdx，不是我的趣味和对此词典的使用方法。
不知道增补本里的新词补编部分有没有文本？如果没有的话，一共99页的补编词汇，大家一起帮忙做也许也能做完 
只是一个想法
fossil的音标在原始光盘里可能就是错的，各mdx版本也如此，纸本无误。
添加“新词补编”我个人认为没有太大价值，1）它不是第四版的内容，翻译也另有其人，不是李北达主编主译的作品，2）这些所谓的新词徒增负担，不属于核心词汇，对外语学习者的作用不是很大，3）如果确实对新词感兴趣，有OALD的8、9、10版，ODE等，不必去求助OALD4。其他则是技术上的困难，OCR中英文混合的复杂文本是很麻烦的，错误一大堆要校对，而且，现在也没有清晰的符合OCR条件的扫描图像，强行OCR，只是自寻苦恼而已。
原来补编内容和原版负责人不同啊，那确实没什么意义了，这些补编词汇其他很多词典也有
稍微了解了一下，fossil的音标写为fɔsl也不能完全说是错误，因为DJ音标不同版本用的字符不一样，见 DJ音标,DJ音标表，各版本DJ音标对照表_英语音标表图片版_巴士英语网
另外，网上流传的那份金山音标转换映射表（ 转换音标字体的音标 ）：
5=ˈ
7=ˌ
9=ˌ
A=æ
B=ɑ
C=ɔ
E=ə
F=ʃ
I=ɪ
J=ʊ
N=ŋ
Q=ʌ
R=ɔ
T=ð
U=u
V=ʒ
W=θ
\\=ɜ
^=ɡ
好像有毛病，起码在牛高4中ʊ、u弄反了，把C和R都转换为 ɔ 肯定也不妥。网上瞎搞的那些玩意看来不能轻信，害人不浅，我自己想一下怎么修复这个问题。
原来dj音标有这么多版
没太了解过
修正牛高4的金山音标字体，我原来用的script是：
#!/usr/bin/env python
# -*- coding: utf-8 -*-
"""
OALD4原始文档音标使用了"Kingsoft Phonetic Plain"字体，
导致不安装该字体的电脑会出现乱码，在此批量替换修正。

现在看来这个映射表用于牛高4有问题，把 “C” 和 “R”都转成了 “ɔ”，“J” 和 “U” 的转换搞反了，“[” 转成 “ɜːr”、“L” 转成 “ər” 也不规范，不是KK音标使用的字符，应该分别为 “ɝ” 和 “ɚ” 。修改后的转换函数应为：
def converter(match):
phonetic_string = match.group()
correct_symbol = phonetic_string.replace('5', 'ˈ')\
.replace('7', 'ˌ').replace('9', 'ˌ')\
.replace('A', 'æ').replace('B', 'ɑ')\
.replace('C', 'ɒ').replace('E', 'ə')\
.replace('F', 'ʃ').replace('I', 'ɪ')\
.replace('J', 'u').replace('N', 'ŋ')\
.replace('Q', 'ʌ').replace('R', 'ɔ')\
.replace('T', 'ð').replace('U', 'ʊ')\
.replace('V', 'ʒ').replace('W', 'θ')\
.replace('Z', 'ɛ').replace('\\', 'ɜ')\
.replace('^', 'ɡ').replace(':', 'ː')\
.replace('[', 'ɝ').replace('L', 'ɚ')\
.replace('?@', 'US').replace('`', 'ˈ')
return correct_symbol
但这个修正后的script是无法直接用于修复OX-7中已有的失误的，用简单替换的方法也不行，因为音标字符再映射回去存在一对多的关系。
我想出来的解决办法是重新生成一份正确的音标字典（dict），然后对OX-7中单词的音标查表替换，音标字典的原始形式略如下所示：
★zero | /ˈzɪərəʊ; ˈzɪro/
★zest | /zest; zɛst/
★zestful | /-fʊl; -fəl/
★zestfully | /-fʊlɪ; -fəlɪ/
★zigzag | /ˈzɪgzæg; ˈzɪɡzæɡ/
★zillion | /ˈzɪlɪən; ˈzɪljən/
★zinc | /zɪŋk; zɪŋk/
★zing | /zɪŋ; zɪŋ/
★Zion | /ˈzaɪən; ˈzaɪən/
★Zionism | /ˈzaɪənɪzəm; ˈzaɪənˌɪzəm/
★Zionist | /ˈzaɪənɪst; ˈzaɪənɪst/
★zip | /zɪp; zɪp/
★Zip code | /ˈzɪp kəʊd; ˈzɪpˌkod/
★zircon | /ˈzɜːkɒn; ˈzɝˌkɑn/
★zither | /ˈzɪðə(r); ˈzɪðɚ/

查表替换则用如下代码：
#!/usr/bin/env python
# -*- coding: utf-8 -*-
import re
def converter(match):
ph_dict ={}
file_erratum = r'C:\Users\xxx\Desktop\ph.txt'
with open(file_erratum, 'r', encoding='UTF-8') as fe:
text_list = fe.readlines()
for row in text_list:
ph_dict[row.split('|')[0]] = row.split('|')[1]
headword = match.group(1)
phonetic = match.group(2)
if headword in ph_dict:
correct_symbol = headword + '\n' + ph_dict[headword].strip() + ' '
print(correct_symbol)
else:
correct_symbol = match.group()
return correct_symbol
def main():
file_src = r'C:\Users\xxx\Desktop\OX-7.txt'
file_dst = r'C:\Users\xxx\Desktop\OX-8.txt'
with open(file_src, 'r', encoding='UTF-8') as f:
text = f.read()
p = re.compile('(★.*?)\n(/.{1,60}?; .{1,40}?/ )')
result = re.sub(p, converter, text)
with open(file_dst, 'w', encoding='UTF-8') as fo:
fo.write(result)
if __name__ == '__main__':
main()
程序本身workable，修正了绝大多数不规范的音标，是否高效再说了。现在的问题是，如何评估这种批量修改造成的潜在误伤？针对这种没有形式化规范过的纯文本数据，正则/程序批量修改我一直是比较忌讳的，尽量少用，但数据量较大，手工一个个修正也不太现实，看来只能折中选择。
用正则“/.{1,60}?; .{1,40}?/”搜索OX-7，返回29177个结果，用“/.{1,60}?; .{1,40}?/ ”（最后加了空格），返回27394个结果，用“^/.{1,60}?; .{1,40}?/ ” （指定以“/”开头），返回26935个结果。说明了牛高4中大概有28000左右个音标，上列“查表替换”script选择最严格的正则表达式，只会修改26935个音标，剩余的1000、2000个音标，只能人工查核纠正了。
这不是说剩下的1000、2000个音标就肯定有问题，这些音标中只有DJ音标部分包含“ɔ、u”（原始形式“C”、“J”），KK音标中包含“ʊ、ɜːr、ər”（原始形式“U”、“[”、“L”）的有毛病，需要进一步人工修正。
针对原始文本可以提供一个思路。先为音标部分加入html标签，用Kingsoft Phonetic渲染音标，保存浏览器中的结果即可，方便快速，100%准确。
你说的这种办法保存出来的结果是错的，依然是“乱码”，自己试试就知道了，私码修改要用（正确的）映射表替换的方法，浏览器只保证渲染效果，不会改变原始数据。而且，给原始文本音标部分加标签工作原理和用正则、程序直接修改音标没什么区别，同样各种误伤与漏改。
还有，牛高4用金山音标字体渲染出来的音标本身有些就是错误的，或者说，不规范，不符合牛高4纸本书的音标标注，像“watch”，金山字体渲染出来的音标是 /wɔtʃ; wɑtʃ/ ，实际上纸版书的音标是 /wɒtʃ; wɑtʃ/ ，“put”金山音标是 /put; pʊt/ ，纸本书上是 /pʊt; put/ ，何以至此，我也不清楚，我校改其文本的原则是尽量符合纸本书原文。
此处的“查表替换”程序存在着一个陷阱，就是英文单词有一词多音现象，python词典（dict）里键值唯一，意味着最终会导致多音词都被修改为同一个靠后的发音，幸好英文里多音词比较少，后面可以人工纠正。
顺手统计了一下，牛高四中的多音词比我设想的多。

牛高四文本真是一个天坑，本来我认为可能没啥大毛病了，没想到接连暴露出两个问题：一是音标转写错误，或者说不规范，不符合原纸本书，原来的“乱码”文本即使使用金山音标字体，渲染出来的音标字符有些也是错的；二则是词条重复，查了一下，计有如下283个重复entry：
