Oh, please give a name for any free font to reproduce your problem.

FT_Face object is bound to the font file or memory image
that you opened. In this case, when you open alial.ttf
and create an FT_Face object once, you cannot disconnect
it from arial.ttf. You should open ariali.ttf as another
FT_Face object.

In addition, the searching of font file - from arial.ttf
to ariali.ttf - is not the task of FT2. Most Unix applications
use fontconfig library to obtain the location of expected
font face.

However, there are many font families that only normal
upright styles are provided (without bold, oblique styles).
Some people want to synthesize embolden/slanted typeface
from normal upright typeface, so FT2 provides
FT_GlyphSlot_Oblique(), FT_GlyphSlot_Embolden() etc.
For detail, please check src/base/ftsynth.c.
