Subject: Make sure that the charcode is signless
X-Git-Tag: archive/raspbian/3.24.39-1+rpi1~1^2~42
X-Git-Url: https://dgit.raspbian.org/?a=commitdiff_plain;h=ed8331efcdc2abd65f8c362017547b4d0dbabe83;p=gtk%2B3.0.git

Make sure that the charcode is signless

1. The data with type of char is signed by default.

2. The byte value of UTF-8 is signless by default.

3. So, if a UTF-8 charcode is stored in a char array, we should cast the
type of its value from char to unsigned char.

Origin: 3.24.39, commit:6dc75b46cc9afe1c98b7ba72a9b1a275c723ea42
