Now if you scroll down you will see that the letters will appear on the site but not when I post it. How do I fix this?

Further information: Runic alphabet#Unicode
The Elder Futhark is encoded in Unicode within the unified Runic range, 16A0–16FF. Among the freely available TrueType fonts that include this range are Junicode and FreeMono. The Kylver Stone row encoded in Unicode reads:
ᚠᚢᚦᚨᚱᚲᚷᚹᚺᚾᛁᛃᛇᛈᛉᛊᛏᛒᛖᛗᛚᛜᛞᛟ
Encoded separately is the "continental" double-barred h-rune, ᚻ. A graphical variant of the ng-rune, ᛝ, is also encoded separately. These two have separate codepoints because they become independent letters in the Anglo-Saxon futhorc. The numerous other graphical variants of Elder Futhark runes are considered glyph variants and not given Unicode codepoints. Similarly, bindrunes are considered ligatures and not given Unicode codepoints. The only bindrune that can arguably be rendered as a single Unicode glyph is the i͡ŋ bindrune or "lantern rune", as ᛄ, the character intended as the Anglo-Saxon Gēr rune.
