w2grid search text supports accented characters but cannot find unaccented matches (é or e)

[AlanSkyNet]

When you set toolbarSearch to true on a grid, if you search on a text field it will miss all matches if there is an accent in the search value.

name: 'gridDocs',
header: 'List of documents',
show: { header : true, toolbar: true, toolbarSearch: true, toolbarReload: false, footer: true},
multiSearch: false,
searches: [
{ field: 'doctitle', label: 'title', type: 'text', operator: 'contains'}
]

It seems like sorting a grid had the same kind of problem until w2ui supported fields with sortMode: 'i18n'.

Filtering search using the same kind of 'replace accented char with base letter' routine should do it.
