custom font problem on jasper server

[zol777]

my jasperserver version :5.5.0

i have follow above some web tutorial  to embedded the ttf file for jasper server . it works

but if i wanna to embedded the ttc file , it is not ok . it  is amazing for me . since i have embedded the ttc file  with jasper report api by using the follow syntax

pdfFontName="c:/a.ttc,1"

Furthermore , i have try to use otf file . but it always return the following error

Font 'NotoTChinese' is not available to the JVM.   

even i have placced  the OTF font file in  the correction location of jasperreports-fonts-5.0.0.jar

so should i confirm that otf and ttc are not supported jasper server

Furthermore , i have found not all ttf can be embedded in pdf for jasper server. can someone provide the hints on detemining which feature of TTF indicated it can be embedded in PDF via jasper server?

my test case : ArialUT.ttf bundled in window 7 are ok to show all character with HKSCS encoding
