[BUG] Use {{var}} instead of {var} to Avoid LaTeX Symbol Conflicts

[zenyanbo]

Describe the feature you'd like Hello, I've noticed that using single curly braces { } can sometimes lead to conflicts with LaTeX symbols in prompt tempalte. To make things smoother, could we switch to using double curly braces {{ }} instead?

Additional context

Benefits:

• Reduces potential conflicts with LaTeX symbols.
• Improves user experience, especially for math-heavy content.

Thanks for considering this improvement!

hmm thats because langchain is using curly bracket syntax {} for prompt values. One workaround for your case is to encode the LaTeX symbol
