I'm using Corel draw.
Recently when I try to type in our local language "Gujarati" via Google Input tools or font installation with Gujarati fonts, the typed text is not showing joined words and characters correctly.
This is a ligature issue. CorelDRAW X4 & X5 doesn't have full ligatures support. Full ligatures (or open type) support was added in CorelDRAW X6.
You need to upgrade to CorelDRAW X6 otherwise for X4/X5 you'll have to use third party language softwares like Akruti, Shreelipi etc.
You should check for more info in a coreldraw community support like this.
