Flat & sharp symbol in chord voicing is wrong

I wasn't able to find any previous topic about this. I'm using a different font for chord symbols and text for jazz lead sheets. I'm using the Jazzcord font, or Jazztext (I've tried both) and in both cases, when inputting chord symbols, the flat and sharp symbols appear to be another font and don't match. Both fonts have a flat symbol in the glyph set and you see that when entering it but then it's changed once I hit enter.

I prefer the look of these fonts to the musejazz font but the flats and sharps make it difficult to read.

Anyway to work around this? PDF of a chart attached.
