Problem writing accents adds a space

Problem writing accents adds a space

Hi, 

I have a problem with zoho docs which I only come across on my mac book pro, and this is every time I write a letter with an accent (á, é, í, ó, ú) the editor's cursor appears a space further separating the word.
I have tried changing the encoding, and several more settings around unsuccessfully.  this happens both in latest chrome and safari version.

Can anyone lend me a hand?

Thank you.

Miguel.
