Here's the rest of the info for "lambda" being composed into "lambda":

             position: 14095 of 224875 (6%), column: 4
            character: l (displayed as l) (codepoint 108, #o154, #x6c)
    preferred charset: ascii (ASCII (ISO646 IRV))
code point in charset: 0x6C
               script: latin
               syntax: w 	which means: word
             category: .:Base, L:Left-to-right (strong), a:ASCII, l:Latin, r:Roman
             to input: type "C-x 8 RET HEX-CODEPOINT" or "C-x 8 RET NAME"
          buffer code: #x6C
            file code: #x6C (encoded by coding system utf-8-unix)
              display: composed to form "lambda" (see below)

Composed with the following character(s) "ambda" by the rule:
	(?λ)
The component character(s) are displayed by these fonts (glyph codes):
 λ: xft:-unknown-Latin Modern Math-normal-normal-normal-*-15-*-*-*-*-0-iso10646-1 (#xF6F)
See the variable `reference-point-alist' for the meaning of the rule.

Character code properties: customize what to show
  name: LATIN SMALL LETTER L
  general-category: Ll (Letter, Lowercase)
  decomposition: (108) ('l')
