It's not clear to me whether you simply get a larger bitmap (i.e.,
more rows), or whether the glyph itself (this is, the rendered black
pixels) is larger...
I'm getting more rows (see sample code).
In case you haven't solved the problem yet please provide a
standalone, *small* demo program for the terminal that exhibits the
issue.
Here is a sample program; and here's the output that I'm getting:
Output:
Num rows (char |): 32
Num rows (char f): 38
