Subject: Properly close a handle. Use a putatively effective runtime test for UTF-8 console... 
X-Git-Tag: version-3.44.0~13^2~1
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=060c097e0d2f947ad77ce12f6781320aec6088f9;p=thirdparty%2Fsqlite.git

Properly close a handle. Use a putatively effective runtime test for UTF-8 console I/O capability. (This makes the version test useful mainly for avoiding a warning that UTF-8 console I/O could not be setup.)
