uim-viqr 1:1.8.8-9.2build4 (amd64 binary) in ubuntu mantic

 Uim is an input method module library which supports various scripts and can
 act as a front end for a range of input methods, including Anthy, Canna,
 or SKK (for Japanese), Pinyin (for Chinese), Byeoru (for Korean), and
 M17n (for many other languages). Most of its functions are implemented in
 Scheme, so it's very simple and flexible.
 .
 This package provides uim support for VIQR (Vietnamese Quoted-Readable)
 input. VIQR is a mnemonic encoding of Vietnamese characters into US ASCII
 for use on 7-bit systems - see RFC1456.
