Issue with the Unicodes of Plane 15-16 (Private User Area Planes)

[THISISSUBBU]

Hi
We are getting issue with the unicode using from the Private User Area Planes.

For example I'm using the Unicode 0xf008d and expected that the glyph should contains the unicode &#xf008d,

But the decoding conversion from ucs2.decode i'm getting the
0xf008d

Idea is to provide a callback or hook to decide which unicode will be placed in the glyph, default one is use the existing unicode decoding.

Can i create a pull request or is there any way to achieve as i expected?

I'm a gentledev i:

• [y] fully read the README recently
• [y] searched for existing issues
• [y] checked i'm up to date with the latest version of the project

Expected behavior

Looking for a hook or callback to provide the unicode

Actual behavior

There is no hook to provide user defined unicode that are in the Private User Area space

Steps to reproduce the behavior

Debugging informations

• Use \uf008d as unicode for the glyph, getting the unexpected result.

0xf008d

• npm -v result:

<paste here>

If the result is lower than 6.9.5, there is
poor chances i even have a look to it. Please,
use the last NodeJS LTS version.
