Defined this way, fontName is a pointer

The macro RTL_CONSTASCII_USTRINGPARAM( constAsciiStr ) expands to

constAsciiStr, ((sal_Int32)(sizeof(constAsciiStr)-1)), RTL_TEXTENCODING_ASCII_US

so that

sizeof( pointer ) - 1

is 4 - 1 (in 32 bit arch.) or 8 - 1 (in 64 bit arch.)

Your OS is 32 bits: (sizeof( pointer ) - 1) is 3, thus "Cor".

Define the string literal as an array:

const char fontName[] = "Corbel";

or simply avoid all these temporal variables:

xPropSet->setPropertyValue(
OUString(RTL_CONSTASCII_USTRINGPARAM("CharFontName")),
makeAny(OUString(RTL_CONSTASCII_USTRINGPARAM("Corbel"))));
