I'm working on a small webapp with a JSON api. I've stumbled across a bug
where I can't POST JSON with a % sign in it or it'll blow up.
for example if i POST this json:
```
{
"foo": "%"
}
```
i get this stack trace
```
[Mon Jan 3 23:08:44 2022] "POST http://localhost:5749/json/sanity-check/
HTTP/1.1" Error: (string->symbol)
bad argument type - not a string
#f
[bunch of irrelevant stuff]
router.scm:249: intarweb#read-urlencoded-request-data
spiffy.scm:509: k625
spiffy.scm:497: g628
spiffy.scm:511: handle-exception
spiffy.scm:512: chicken.port#with-output-to-string
```
(router.scm is mine)
Unfortunately that section of spiffy is a long and complex method and the
error handler is surrounding a LOT of functionality, so it's not clear to
what's blowing up.
I tried bringing the uri-common.scm (since it seems plausible that this is
a decoding issue) and spiffy.scm into my project and compiling them into
the app (one at a time) but I always end up with this error:
```
Error: during expansion of (import-syntax ...) - unbound variable: ����
```
I'm happy to debug things but I could really use some help. Maybe if
someone could tell me the magic incantation to include a file from an egg
without that error so that I could then start breaking it down and
eliminating problems?
Any insight would be appreciated.
Thanks.
