Contains Unicode codepoints, loading as needed from YAML files
Returns string with its UTF-8 characters transliterated to ASCII ones
You're probably better off just using the added String#to_ascii
# File lib/stringex/unidecoder.rb, line 15 def decode(string) string.gsub(/[^\x00-\x00]/) do |codepoint| if localized = translate(codepoint) localized else begin unpacked = codepoint.unpack("U")[0] CODEPOINTS[code_group(unpacked)][grouped_point(unpacked)] rescue # Hopefully this won't come up much # TODO: Make this note something to the user that is reportable to me perhaps "?" end end end end
Returns character for the given Unicode codepoint
# File lib/stringex/unidecoder.rb, line 33 def encode(codepoint) ["0x#{codepoint}".to_i(16)].pack("U") end
Returns Unicode codepoint for the given character
# File lib/stringex/unidecoder.rb, line 38 def get_codepoint(character) "%04x" % character.unpack("U")[0] end
Returns string indicating which file (and line) contains the transliteration value for the character
# File lib/stringex/unidecoder.rb, line 44 def in_yaml_file(character) unpacked = character.unpack("U")[0] "#{code_group(unpacked)}.yml (line #{grouped_point(unpacked) + 2})" end
Returns the Unicode codepoint grouping for the given character
# File lib/stringex/unidecoder.rb, line 56 def code_group(unpacked_character) "x%02x" % (unpacked_character >> 8) end
Returns the index of the given character in the YAML file for its codepoint group
# File lib/stringex/unidecoder.rb, line 61 def grouped_point(unpacked_character) unpacked_character & 255 end
# File lib/stringex/unidecoder.rb, line 51 def translate(codepoint) Localization.translate(:transliterations, codepoint) end
