Question

Could a checker be built for this cache? GC3C2Z7 Thanks

Answer 1

Seems to be feasible:

To complete this challenge you need find 25 caches that have names / titles that start with anything other than a letter, number, or space.

You have made a small mistake in the checker. There are more letter then A-Z
17 of the 25 caches in the challenge for me starts with Å Ä Ö and they are letters
Not used in the english alphabet but still letters
You now have the interesting problem that cache names are utf-8 and lua pattern dont support that

It is really vague definition what is letter. But taking it the other way round is also not a good idea (the mentioned UTF8) :/ I added your Swedish (?) letters and some from around here. Let me know if you can think of some other.

Unfortunately the %a does not work in this case.

Yes it is Swedish Æ, Ø are used in Danish and Norwegian.
I suspect the to upper-case function don't work correctly ether but few caches starts with lower-case letters
The only one i found was älgen http://coord.info/GC2BDM8
But when i tested the checker for that cache wit a user with few find Rottafia i noticed that thee was no no listing of qualifying caches when the requirement is not met.The missing row is empty.

I would like if there was a output of ok find even if i fail. Because if you test is and fail and you see caches and just not a number it feel that you have done something and I would be more inspired to complete the challenge. An if you are logging caches to meat the requirement it is nice to be able to look and see new caches added.
My checkers often outputs a best result if you fail because it is fun to se when you almost did it
In this case incorrect ok find can also be detected

I tested som of the finds of the cache and only found one error

and had logged with     ווארענונג - Varenung - CITO that starts with a Hebrew ג(Gimel) or a ו(Vav) depending of how left right test are interpreted


But i suspect that if all letters used in Spanish (when the cache in in Texas) is included there will not be a big problem. in the wiki page i could find that a keyboard should have
 á, é, í, ó, ú, ñ, Ñ, ü, Ü, ¿,  ¡. Á, É, Í, Ó, and Ú
Some of the upper case are missing in your checker and should be added

Thanks for comments. I modified checker to report what you have so far if you don't fulfil the requirements completely. I create it long time ago.

Not sure if Æ, Ø might be even considered as a letters in some countries :) But yes, you are right, they should be there. I added also the other I missed.

I am not too confident about the hebrew or chines letters. There is too much of them and I hope they are not too common in the US.

Thanks for the checker.  I found it quite useful.
