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)

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
