If you follow the link given in the documention of
`FT_ENCODING_MS_SYMBOL', you would eventually reach

  
https://docs.microsoft.com/en-us/typography/opentype/spec/recom#non-standard-symbol-fonts

which says

  The 'cmap' subtable (platform 3, encoding 0) must use format 4.  The
  character codes should start at 0xF000, which is in the Private Use
  Area of Unicode.  It is suggested to derive the format 4 encodings
  by simply adding 0xF000 to the format 0 (Macintosh) encodings.

So simply add 0xF000 to your character code values.
