@ -97,14 +97,12 @@ will exhibit rendering problems. Those rendering problems arise from Vty
and the terminal emulator coming to different conclusions about how wide
some characters are.
Vty has a built-in Unicode character width table. Unless configured to
do otherwise, by default, Vty will use this built-in table. But since
the built-in table is likely to eventually disagree with your terminal,
Vty provides a feature called custom Unicode character width table
support. This feature allows Vty to query your terminal to build a width
table based solely on your terminal emulator's logic. That table is then
saved to disk and loaded by Vty-based applications to ensure that Vty's
width calculations are correct for that particular terminal.
To address this, Vty supports loading custom character width tables
that are based on the terminal's behavior in order to eliminate these
disagreements. By default, though, Vty will use its built-in Unicode
character width table. Since the built-in table is likely to eventually
disagree with your terminal, Vty provides an API and a command-line tool
to generate and install custom tables.
Custom Unicode width tables based on your terminal emulator can be
built by running Vty's built-in tool, `vty-build-width-table`. The tool
