 ## String Convention
 
-Unless noted otherwise (for hex pubkeys and ids), the module passes strings to the host as `(ptr: i32, len: i32)` pairs into its linear memory. The host returns strings (and other variable-length data) by returning an `i32` pointer to a buffer in linear memory whose first 4 bytes are the `u32_be` byte-length of the payload that follows.

The host returns strings (and other variable-length data) by returning an `i32` pointer to a buffer in linear memory whose first 4 bytes are the `u32_be` byte-length of the payload that follows.
 
 For example, if `nostr.get_content(handle)` returns `7165` that will be a pointer to a buffer at location `7165`. If that buffer starts with `[ 00 00 00 03 ]` that means it contains 3 bytes (aside from the initial four), so we can keep reading it `[ 00 00 00 03 66 6f 6f ]` and conclude that the string is `"foo"`.

 Hosts may deduplicate filter values (authors, ids, kinds, and tag values) when the module adds the same value more than once via `req_add_*`.
