How can I repace double backslash with '\space'?

[瞬间空白]

Describe the bug:
Hi, I was migrating MathJax to KaTex, but I found that they handle whitespace differently. For example,
$\\frac{1}{6}(\\ \\ \\ \\ )$, It was rendering like this

How can I repace double backslash with '\space'? Or is there any way to fix this problem?

Looking forward to your reply.

(La)TeX code:
The code of (La)TeX you tried to render:

$\\frac{1}{6}(\\ \\ \\ \\ )$

Expected behavior:

Environment (please complete the following information):

• KaTeX Version: 0.16.8
• Device:Desktop
• OS: Mac
• Browser: Chrome
• Version: 115.0.5790.114

Presumably you've got double backslashes because you're feeding KaTeX via a javascript string, correct? It's not really clear why your "double backslash space" is not giving you what you expect here. perhaps you could use a regex to handle the replacement properly, before passing the string to KaTeX?

Or why not avoid the issue altogether and just make use of \hspace like this: \frac{1}{6}(\hspace{0.6cm}). This gives us:

Thanks for your advice, I used a string to render a formula and I solved this problem with regex before passing. Due to historical reasons, we have a lot of data like this, and the \ in mathjax means a space but in katex it just renders a \.
