themselves in the nascent commercial Linux market, Corel also developed their own distribution of Linux. This included WordPerfect 8.1 for Linux. Although the Linux distribution was fairly well-received, the response to WordPerfect for Linux varied. Some Linux promoters appreciated the availability of a well-known, mainstream application for the operating system. Once OpenOffice.org appeared in 1999, there was little demand for a proprietary, closed-source project like WordPerfect. On top of this, WordPerfect 9.0, which was released as part of the WordPerfect Office 2000 for Linux package, was not a native Linux application like WP 6–8, but derived from the Windows version using Corel's own version of the Wine compatibility library, and hence had performance problems. WordPerfect failed to gain a large user base, and as part of Corel's change of strategic direction following a (non-voting) investment by Microsoft, WordPerfect for Linux was discontinued and their Linux distribution was sold to Xandros. In April 2004, Corel re-released WordPerfect 8.1 (the last Linux-native version) with some updates, as a "proof of concept" and to test the Linux market. , WordPerfect for Linux is not available for purchase; however, it can still be found used, in online marketplaces.

Linux applications may use the libwpd library to convert WordPerfect documents. iOS A WordPerfect X7 app for iOS was released in 2014, but it was merely remote desktop software that connected to a Corel-hosted WordPerfect for Windows session. It was billed as a "Limited Free Trial" and was eventually discontinued by Corel. Unicode and Asian language editing WordPerfect lacks support for Unicode, which limits its usefulness in many markets outside North America and Western Europe. Despite pleas from long-time users, this feature has not yet been implemented. For users in WordPerfect's traditional markets, the inability to deal with complex character sets, such as Asian language scripts, can cause difficulty when working on documents containing those characters. However, later versions have provided better compliance with interface conventions, file compatibility, and even Word interface emulation. However, WordPerfect X4 was reported to be able to import IPA character set, and copy and paste works as long as the pastes into WP are done via Paste Special > Unicode command. Publishing to PDF from WordPerfect embeds the WP-phonetic font together with the Unicode-compatible font. Reception PC Magazine stated in March 1983 that "WordPerfect
