Patch 7.2.109
Problem: 'langmap' does not work for multi-byte characters.
Solution: Add a list of mapped multi-byte characters. (based on work by
Konstantin Korikov, Agathoklis Hatzimanikas)
Files: runtime/doc/options.txt, src/edit.c, src/getchar.c, src/macros.h,
src/normal.c, src/option.c, src/proto/option.pro, src/window.c

be able to execute Normal mode commands.
This is the opposite of the 'keymap' option, where characters are
mapped in Insert mode.
- This only works for 8-bit characters. The value of 'langmap' may be
- specified with multi-byte characters (e.g., UTF-8), but only the lower
- 8 bits of each character will be used.
Example (for Greek, in UTF-8): *greek* >
:set langmap=ΑA,ΒB,ΨC,ΔD,ΕE,ΦF,ΓG,ΗH,ΙI,ΞJ,ΚK,ΛL,ΜM,ΝN,ΟO,ΠP,QQ,ΡR,ΣS,ΤT,ΘU,ΩV,WW,ΧX,ΥY,ΖZ,αa,βb,ψc,δd,εe,φf,γg,ηh,ιi,ξj,κk,λl,μm,νn,οo,πp,qq,ρr,σs,τt,θu,ωv,ςw,χx,υy,ζz
