I'm trying to use the Plex Sans Thin font on my android device as a replacement for Roboto. Everything but the lockscreen clock looks great. I looked around a bit and i think this is caused by a missing codepoint for the raised colon discussed here

Heres a picture of what the font looks like without the colon:

Would you please consider including the symbol for increased compatibility of your font?
