mapping the Unicode character with a glyph identifier; and

storing the mapping of the Unicode character with the glyph identifier in a character to glyph correspondence table.

4. The method as described in claim 1 , wherein the font character is accessible via a glyph index that indexes a plurality of font characters.

5. The method as described in claim 1 , further comprising:

applying a digital effect to the segmented digital image, the digital effect including digital smoothing or a digital color overlay.

6. The method as described in claim 1 , wherein the generating of the segmented digital image comprises:

generating cells within a boundary indicator associated with the facial region, the cells overlaying the facial region;

generating markers associated with the cells;

identifying an overlapping portion within the boundary indicator based on the markers; and

extracting the overlapping portion within the boundary indicator.

7. The method as described in claim 6 , further comprising implementing a partitioning algorithm on the overlapping portion.

8. The method as described in claim 6 , wherein the markers include an arc shape or a circular shape.

9. In a digital content rendering environment, a system comprising:

a vector graphic generation module implemented at least partially in hardware of the computing device to generate a vector graphic based on the segmented digital image by converting a format of the segmented digital image into a vector graphic format, the vector graphic including the object that is the facial region of the user; and

a font character generation module implemented at least partially in hardware of the computing device to generate a font based on the vector graphic that includes the object that is the facial region of the user.

10. The system as described in claim 9 , wherein the font character generation module generates the font character based on the vector graphic by mapping the vector graphic to a Unicode character.

11. The system as described in claim 10 , wherein the generating of the font character by the font character generation module further comprises:

mapping the Unicode character with a glyph identifier; and

storing the mapping of the Unicode character with the glyph identifier in a character to glyph correspondence table.

12. The system as described in claim 9 , wherein the font character is accessible via a glyph index that indexes a plurality of font characters.

13. The system as described in claim 9 , further comprising:

a digital effect inclusion module implemented at least partially in hardware of the computing device to apply one or more digital effects to the segmented digital image, the one or more digital effects including one or more of digital smoothing or digital color overlay.

14. The system as described in claim 9 , wherein the segmentation module segments the digital image by:

generating cells within a boundary indicator associated with the object, the cells overlaying the object;

generating markers associated with the cells;

identifying an overlapping portion within the boundary indicator based on the markers; and

extracting the overlapping portion within the boundary indicator.

15. The system as described in claim 14 , wherein the segmentation module is further configured to implement a partitioning algorithm on the overlapping portion.

16. The system as described in claim 14 , wherein the markers associated with the boundary indicator include an arc shape or a circular shape.
