Specimen images don't show U+1D4C1 despite the character being supported

[jmcwilliams403]

It appears to show a duplicate ℒ in an unallocated gap in the block but not the lowercase 𝓁 which is the character that actually does have two official duplicate allocations in Unicode.
Specimen:

The two script lower l's in unicode that are both supported in the actual font but not both shown in the specimen:
ℓ𝓁

In particular, the only two script characters that do indeed have real official duplicate bindings are ℓ/𝓁 and ℘/𝓅

Also as a side-note/tangent, ℒ isn't the only character which shows unofficial duplicate bindings in unallocated gaps in the block in the specimen:

I'll tidy up this section as it appears somewhat disorganized.
I'll duplicate the glyphs to fill the empty spaces, regardless of Unicode standards.
