PDFBox ERROR Could not load font file

I am unsure if it is a PDFBox issue. But mentioning it might help understand my issue.

So I have been getting a lot of these warnings coming from PDFBox:

WARN  No Unicode mapping for a37 (37) in font TCBLZV+LCIRCLE10

This is one out of 100s.

So I decided to add the LCRICLE10 font and other fonts that are mentioned in the warning list.

Here are the fonts I downloaded:

Here is the PDFBox error I am getting:

It's one out of many others.

Here is small list:

ERROR Could not load font file: /home/$USER/.fonts/bakoma/pfb/eufm6.pfb
ERROR Could not load font file: /home/$USER/.fonts/bakoma/pfb/euex9.pfb
ERROR Could not load font file: /home/$USER/.fonts/bakoma/pfb/eusm10.pfb
ERROR Could not load font file: /home/$USER/.fonts/bakoma/pfb/cmmi7.pfb
ERROR Could not load font file: /home/$USER/.fonts/bakoma/pfb/msam6.pfb

They seem to all come from: .fonts/bakoma/pfb/

When I went on FireFox I saw this:

I removed the fonts from ~/.fonts/ and clear the font cache and now everything is back to normal.

The "WARN No Unicode mapping" messages are only relevant if you do text extraction, i.e. your text will be nothing for that glyph because the unicode mapping is missing. "TCBLZV+LCIRCLE10" indicates an embedded font subset, so adding fonts won't help anyway. See also this: https://pdfbox.apache.org/2.0/faq.html#notext

So your real question ends there, it doesn't get better by loading fonts, unless you'd have trouble with non-embedded fonts.

The error "Found Token[kind=NAME, text=dup] but expected INTEGER" indicates an error parsing a type 1 font. This can be a syntax error in the font, or a bug in the PDFBox type 1 font parser. I rather suspect the later, because type 1 fonts are based on PostScript and the PDFBox parser can recognize only a subset of it.

Update: I looked at the eurb9.pfb font. It is like I suspected, the ASCII part of the font has a calculation ("dup dup 161 10 getinterval 0 exch putinterval dup dup 173 23 getinterval 10 exch putinterval dup dup 127 exch 196 get put readonly def") and we can't parse it. Our own type 1 parser can only parse elements that don't calculate. (This still covers 99% of type1 fonts)
