Special characters in notes not properly handled

It seems that special characters in notes are not being handled properly. For example, I typed the following note:
<rdfs:comment xml:lang="λp">
it is controlled by isc-nirscan software under windows os (usb connection) or with an app (ios and adroid, using bluetooth connection). nir measurements will be collected directly, taking a portion of the sample and placing into the cuvette in the spectral range of 900–1700 nm, by accumulating 10 internal scans.">NIR spectra will be collected using a portable NIR spectrometer in the range [900nm, 1700nm]. The sensor NIRvascan ASP-NIR-M T (Allied Scientific Pro) sensor, employs a 1 mm InGaAs datector (Hamamatsu model G12180-010A) Dark Current 0.8nA @vr=1V Noise Equivalent Power 1.4*10-14

However, after saving, the content is displayed incorrectly as follows:

@Bilelkihal didn't see here the issue, can you point to only the text part that was not well printed in you example.

In the API we do save the value correctly. So the sanitization most be done somewhere in the UI.
