Leading junk in OCLC numbers

[daniel-barrows]

Sometimes Citer includes leading junk characters in the oclc parameter.

Examples:

• https://citer.toolforge.org/?user_input=9780674022188 includes oclc=ocm62134798
• https://citer.toolforge.org/?user_input=978-80-210-8779-8 includes oclc=on1021182894

In all cases, the correct OCLC number is the numbers without the leading letters.

I have observed examples but I did not record them.

Note: Citer sometimes includes OCLC numbers in output and sometimes doesn't. My guess is that is related to OCLC usage limits and is not a bug, but it may make verifying this problem difficult.

Interesting! This is actually coming from Citoid API:
https://en.wikipedia.org/api/rest_v1/data/citation/mediawiki/978-80-210-8779-8
(It took me several retries to get an output with OCLC which explains the erratic results)

I've Implemented a quick fix which is not deployed yet.

The issue needs to be reported upstream (https://phabricator.wikimedia.org/project/view/62/) to see if it can be fixed there, I'll leave this open until then.
