In any browser go to http://bm.m.wikipedia.org/wiki/Nyɛ_fɔlɔ and tap the 'W' icon. Tap desktop view. You'll be taken to http://bwikipedia.org/w/index.php?title=Ny%C9%9B_f%C9%94l%C9%94&useformat=desktop which does not exist. Looks like our regex is over zealous with stripping 'm' s.
Looking at https://meta.wikimedia.org/wiki/List_of_Wikipedias and found tum, om, bm, sm (100+), cbk-zam, udm, km, rm, pam (1000+) and am (10,000+) which may help with testing.
I've just spent about 30 minutes looking into this and I can't replicate this on my local machine... was this already fixed or is there something odd going on somewhere?
Resolved in https://gerrit.wikimedia.org/r/#change,4291 - will be deployed shortly.
Merged to deployment branch and deployed at r114716. Original example given tested and confirmed working now.
