Incorrect Japanese transliteration for っ

[fluffy-critter]

っ is U+3063 HIRAGANA LETTER SMALL TU, which is different than つ U+3064 HIRAGANA LETTER TU in that the phonetic transliteration of it is a glottal stop; the English equivalent is doubling the consonant-sound of the next mora.

For example, ほっこり should be transliterated as 'hokkori', but awesome-slugify incorrectly renders it 'hotsukori' (as if the っ were a つ):

>>> slugify('ほっこり')
'hotsukori'
