我的 Tex 文件中的一些 UTF-8 字符有问题。尽管我以 UTF-8 保存文件，并且我的文本编辑器 (Atom) 可以正确显示所有字符，但 LaTeX 会抛出如下错误：
[no file]:824: Package inputenc Error: Unicode character Δ (U+394) [...tes $(x,y)$ are $x=x_0+Δx$ and $y=y_0+Δ]
[no file]:857: Package inputenc Error: Invalid UTF-8 byte sequence. [ # calculate ω]
[no file]:857: Package inputenc Error: Invalid UTF-8 byte 137. [ # calculate ω]
[no file]:889: Package inputenc Error: Unicode character θ (U+3B8) [...ce $r$. It was previously at an angle $θ]
[no file]:889: Package inputenc Error: Unicode character ω (U+3C9) [...ngle $θ$ and is now at an angle $θ + ω]
[no file]:976: Package inputenc Error: Invalid UTF-8 byte sequence. [ # calculate ω]
我尝试使用 utf（和 utfx）包但无济于事：
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
以下是整个文件的内容：https://pastebin.com/dzzLtUmB。
由于格式是生成的，所以看起来可能有点粗糙。
我能做些什么来修复这个问题吗？
答案1
如果我添加draft乳胶，则乳胶不会在缺失的数字处停止，由于数学模式标记不正确，会出现几个错误，并且需要重新定义一些 utf8 字符，但您不会收到错误
[no file]:976: Package inputenc Error: Invalid UTF-8 byte sequence. [ # calculate ω]
我怀疑你有一个较旧的 latex 版本，并且在 UTF8 解码器中遇到了错误，可能

确保你拥有最新的乳胶。
