Pinyinated 'm' with four tone marks? I know 'm' is a pinyin pronunciation. Looking through my dictionaries I've seen it listed in first, second and fourth tones. I can't seem to find the correct accented lower-case 'm's anywhere though...

Tone marks are as follows:


1st tone = ˉ (macron)
2nd tone = ˊ (acute accent)
3rd tone = ˇ (caron/háček)
4th tone = ˋ (grave accent)


So basically what I'm asking is where can I find:


lower case m with macron
lower case m with acute
lower case m with caron/háček
lower case m with grave


anyone?
Tones are only applied to wovels. There are no tones associated with consonant "m", so you have to assume a prefix wovel like "e" before the "m". Unicode-wise, you can get an accented ḿ but no other variants.

Yes, you see accented "m" in dictionaries, but they are outside pinyin, and also outside unicode.
