Getting the above issues with chrome and safari whereas, in Firefox it is working fine. 使用chrome和safari可以解决上述问题,而在Firefox中可以正常工作。
The above issue occurs only in - webkit web browsers like chrome and safari - which provides support for ligatures - whereas browser like firefox does not. 仅在-chrome和safari之类的webkit Web浏览器-提供对连字的支持-而像firefox之类的浏览器却没有这种情况时,才会发生上述问题。
A ligature is a combination of two or more letters joined as a single glyph
连字是两个或多个字母组合成单个字形的组合
Root cause 根本原因
This issue with missing characters is due to ligature support provided by these modern browsers - let me explain how 缺少字符的问题是由于这些现代浏览器提供的连字支持-让我解释一下
1.The tool while converting - it converts characters to glyphs using poppler for rendering - now these browser when they come across characters like tt tf ti ff fi consider them to be ligature and searches for glyphs corresponding to tt and not tt 1.转换时的工具-它使用poppler将字符转换为字形以进行渲染-现在这些浏览器遇到诸如tt tf ff ff之类的字符时,会认为它们是连字并搜索与tt而不是tt对应的字形
2.Since they do not have their corresponding glyphs - they just skip the characters and renders the rest - so, we fount the characters missing 2.由于它们没有对应的字形-他们只是跳过字符并渲染其余字符-因此,我们发现缺少的字符
Could be solved by 可以解决
Disabling/ Turning-off the ligature in these browsers - embedding the css in the generating content 在这些浏览器中禁用/关闭连字-将CSS嵌入到生成的内容中
