This is a table similar to Wikipedia’s zhuyin table, but with slightly different sorting and an example for each possible combination of initials and finals.

This table leaves out two finals that never combine alone with any nonempty initial: ㄝ and ㄦ (二、兒、耳、而, etc.). ㄝ never appears alone, and couldn’t be transcripted into pinyin anyway, since e alone is taken by ㄜ.

The highlighted combinations are ones I find to be unusual or unique:

• ㄔㄨㄚ: 欻/歘 — [onomatopoeia] sound of heavy steps; 䫄 — strong-looking. Likely uncommon, since my desktop keyboard layout doesn’t present these options.
• ㄋㄡ: 耨、鎒 — [literary] a weeding hoe; 䨲 — [obsolete] a young hare; 獳 — [obsolete] an angry dog. None of these seem to be in common use.
• ㄌㄩㄢ: 孿 — twins; 孌 — beautiful or docile; 臠 — [literary] a small piece of meat; 癵 — bent or crooked (of the body). These alternatively appear to be pronounced as ㄌㄨㄢ.
• ㄘㄣ: 岑 — [literary] a high hill; 涔 — [literary] rainwater in puddles. My desktop keyboard layout gives a few more options, but none of them seem to be common.
• ㄋㄨㄣ: 黁 — fragrant, used in the phrase 溫黁; no other homophones.
• ㄅㄧㄤ: 𰻞 — specifically used for 𰻞𰻞麵.

The order of initial consonants are grouped by how similar to one another they behave, so it’s easy to spot where combinations are unexpectedly missing by looking at where ❌s appear outside of big blocks. Notable ones include:

• ㄊㄟ、ㄎㄟ、ㄋㄨㄟ、ㄌㄨㄟ don’t exist, but other -ㄟ and -ㄨㄟ around them do.
• Conversely, ㄕㄟ（誰）、ㄗㄟ（賊）exist, but not ㄙㄟ、ㄓㄟ.
• ㄅㄡ、ㄊㄧㄡ don’t exist, but other -ㄡ and -ㄧㄡ around them do.
• ㄅㄜ、ㄆㄜ don’t exist, but ㄇㄜ˙（麼）does.
• ㄌㄣ doesn’t exist, despite the existence of both nearby ㄋㄣˋ（嫩）and ㄌㄨㄣˊ（輪）.
• ㄕㄨㄥ doesn’t exist, despite the existence of the uncurled ㄙㄨㄥˋ（送）.
• ㄈ- has the fewest combinations, with only eight possible ones.
