hi Behdad the proposed method sounds quite interesting and useful. For font developers, I think it will add the power to fine-tune the font selections, particularly for massaging CJK fonts with Latin fonts. I would like to give my full support on this effort. In addition, I am not quite sure if this could be a possible remedy for the common-script contextual formating issue that we have discussed earlier (please forgive me if the connection is obvious) https://www.redhat.com/archives/fedora-fonts-list/2007-December/msg00013.html if they are connected, can you illustrate one scenario where this mechanism can help to constrain the fonts for Common Scripts? thank you Qianqian Behdad Esfahbod wrote: > Hi, > > This keeps coming up again and again: CJK users want Pango to choose > Latin fonts differently under a CJK locale than it does under a non-CJK > locale. > > Making that work is currently impossible in Pango+fontconfig.
