Good afternoon,
I must say that I found out that there are several issues on Wikimedia Commons. While adding some character and trying to add symbol (=, +), some weird IPA symbols appear sometimes, instead of what I want. I'll show it: ʍ instead of w=, ə/e=, ɹ/r=, θ/t=, ʒ/z=, ɯ/u=, ɪ/i=, ɒ/o=, ʘ/p=, ɑ/a=, ʃ/s=, ð/d=, ɸ/f=, ɣ/g=, ɥ/h=, ɟ/j=, ɬ/l=, ʏ/y=, χ/x=, ç/c=, ʋ/v=, β/b=, ɲ/n=, ʡ/Q=, ɘ/E=, ʀ/R=, ʉ/U=, ɨ/I=,ɵ/O=, ɢ/G=, ʜ/H=, ʟ/L=, ʙ/B=, ɴ/N=, ̟/+, ̝/++, ̘/+++ etc. (more += more weird signs, also errored when combined with letters). It only doesn't happen to q, k, m, W, T, Z, P, A, S, D, F, J, K, Y, X, C, V, M. Thanks for fixing.
I will try to describe it more cleverly: When you type some certain characters (=, +, :), the result what you get is really weird, because there are several bugs: when you combine = with some letter, the letter will change into some IPA symbol, if you write +, you will get ̟, (this will change and then multiply while adding more +, combinable with ALL possible characters), if you write :, you will get ː, or ˑ, when multiplied. It is not a bug of keyboard, because it doesn't happen on any other wiki. I'm reporting it, because it worses and makes uncomfortable writing on Commons. I also took a screenshot, see there: https://commons.wikimedia.org/wiki/File:%CC%9FC%CB%90%C9%92mm%CC%9Do%C9%B2s_%CC%B9%CC%B9%CC%9FError.png
