Handling bad variable identifiers

[Sagebati]

Hi,

Little question, in our app we handle a lot of "dynamic" templates supplied by users, sometimes they use invalid characters as vairables {{ é }}. With this kind of input the render crashes, is there a way to handle this kind of error ?

Many thanks for your work and cool library.

In this particular case you can enable the unicode feature which makes such valid variable names valid. And yes, you can normally handle that error by matching on the return value and inspect the Err(..).
