tkmore man page

Besides standard X11 options like -font, tkmore supports:

-i

Turn on case-insensitive search. Alias: -ignore-case.

-encoding encoding

Specify the encoding for the specified file and all subsequently loaded files. By default no encoding is assumed.

-S

Set wrap mode to none. The effect is similar like the -S option of less.
