More careful IPA emphasizes this by not transcribing it as the sequence of characters /dʒ/, though doing so is still common. For a while the solution was to use a ligature, /ʤ/, to emphasize that it was a single consonant, not a sequence of two consonants, but that was typographically to difficult to distinguish from /dʒ/, so now /d͡ʒ/ is preferred, using the generic IPA kludge for "these two characters should be treated as one".
