Plane1Converter.conv("Plane1Converter", :fraktur)

which gives:

[source,console]

• The first argument is a string; all ASCII alphabetic characters (and, if supported, numeric characters, and Greek characters) are converted to the Unicode Plane 1 https://en.wikipedia.org/wiki/Mathematical_Alphanumeric_Symbols[Mathematical Alphanumeric Symbols] character corresponding to the font shift named in the second argument. The gem also supports the https://en.wikipedia.org/wiki/Enclosed_Alphanumerics[Enclosed Alphanumerics] and https://en.wikipedia.org/wiki/Enclosed_Alphanumeric_Supplement[Enclosed Alphanumeric Supplement] blocks, and, circled numbers in https://en.wikipedia.org/wiki/Dingbat[Dingbats],

• Characters are assumed to be in UTF-8; if characters are escaped for representation in ASCII, they need to be converted to UTF-8 before being passed to this gem.

• The string is converted one character at a time: multi-character dingbats such as DINGBAT CIRCLED SANS-SERIF NUMBER TEN (U+2789) (➉) are not supported.

• Other characters mapped to Mathematical Alphanumeric Symbols are also supported, including: ** U+0131 LATIN SMALL LETTER DOTLESS I (ı) ** U+0237 LATIN SMALL LETTER DOTLESS J (ȷ) ** U+03F4 GREEK CAPITAL THETA SYMBOL (ϴ) ** U+2207 NABLA (∇) ** U+2202 PARTIAL DIFFERENTIAL (∂) ** U+03F5 GREEK LUNATE EPSILON SYMBOL (ϵ) ** U+03D1 GREEK THETA SYMBOL (ϑ) ** U+03F0 GREEK KAPPA SYMBOL (ϰ) ** U+03D5 GREEK PHI SYMBOL (ϕ) ** U+03F1 GREEK RHO SYMBOL (ϱ) ** U+03D6 GREEK PI SYMBOL (ϖ) ** U+03DC GREEK LETTER DIGAMMA (Ϝ) ** U+03DD GREEK SMALL LETTER DIGAMMA (ϝ)

• If a character is not supported in the specified font shift, it is left as is.

• Legal values supported for the second argument are: :fraktur:: Fraktur Normal :frakturbold:: Fraktur Bold :monospace:: Monospace :doublestruck:: Double-Struck :script:: Script :scriptbold:: Script Bold :circled:: Circled :circledblack:: Circled Black :squared:: Squared :squaredblack:: Squared Black :serifbold:: Serifed Bold :serifitalic:: Serifed Italic :serifbolditalic:: Serifed Bold Italic :sans:: Sans-Serif :sansbold:: Sans-Serif Bold :sansitalic:: Sans-Serif Italic :sansbolditalic:: Sans-Serif Bold Italic

• Illegal values for the second argument will raise an error.
