Ignore case fails "The Turkey Test"

[subchannel13]

Turkish culture has curious capitalization behavior of the letter "i". They have two "i"s, dotted and dot-less and changing the case preserves the "dotness", in other words "i" is not lowercase "I". More info about the Turkey test can be found here:

In Coco.atg, line 211 uses culturally sensitive ToLower which causes faulty behavior of IGNORECASE.
